Description

The present invention relates to a sound addressing quiz.

Difficulty setting techniques such as changing the tone color and setting chords have been proposed for the sound addressing quiz. The technique of practicing sound quizzes and the like using mechanical means such as AI is meaningful. This is because it is possible to solve the inconvenience of not being able to practice without having an instructor ask questions.
Further, for load control in general, a technique for personalizing a practice load by AI control has been proposed.

Japanese Patent Application No. 2010-30462 Special application flat 3-232045 Japanese Patent Application 2016-111773

The timbre change for the sound addressing quiz is, in other words, a change in how to set a question in which a certain fundamental component is included with overtone components and other frequency components. The difficulty of the sound assignment quiz changes depending on the tone color change, because it is relatively easy for the practitioner to determine the tone color that he or she is familiar with, but it is relatively difficult to determine the tone color that the practitioner is not familiar with. It is due to a reason. In general, it may be said that as the number of frequency components contained in a sound increases, it becomes more difficult to discern all the frequency components, but depending on the overtone components contained, the fundamental tone itself is not necessarily discriminated. It does not have the property of being difficult to distinguish. For example, no matter how complicated the frequency components contained in the piano sound, for those who are accustomed to listening to the piano sound, the complex sound is as simple as the sound of the piano that they are accustomed to listening to. Will be recognized by.

A chord-related sound quiz can also be said to be a task of determining what kind of overtones or components close to overtones are added to a certain fundamental tone. In other words, it can be said that discerning the type of chord has the same property as discriminating the type of timbre. For example, in general, it is easy to discern a chord that you are familiar with and its constituent notes, but it is relatively difficult to discern a chord that you have never used and its constituent notes. Also, for example, when listening to the sound of a major chord, it is easy to determine that it is a major chord rather than a minor chord. In this way, the discernment task related to timbre and chords has a strong aspect as a qualitative task.

From the viewpoint of personalizing the practice load using AI, it is preferable that the load applied to the difficulty setting of the practice is a quantifiable load. It can be said that there is a problem as to what kind of load factor should be focused on in quantitatively defining the difficulty level of the sound addressing quiz system.
By the way, in addition to the timbre of the sound to be asked, the interval of the question sound candidates can be a load that influences the result of the quiz. For example, the task of discriminating the three adjacent Sidre sounds is more difficult than the task of discriminating the three sounds of the do sound, the do sound one octave higher, and the do sound one octave lower. In comparison, the latter can be explained because the interval between question sound candidates is narrower.
It is more difficult to discriminate the three notes of the adjacent chromatic scale (such as Dodo # re) than to discriminate the three notes of the domiso, but the task of reproducing the fine pitch in cents is more difficult than the task of discriminating the chromatic scale. However, it can be said that it is difficult in that a finer sound feeling is required.
In addition to the method of setting chords consisting of multiple sounds, a musical phrase consisting of multiple sounds is given, and the phrase length (the number of sounds contained in the phrase and the phrase presentation tempo) is adjusted to assign the sound. There can be a method of adjusting the load of the quiz. For example, the task of reproducing a phrase consisting of multiple notes is more difficult than the task of reproducing a single note given. In general, when the phrase presentation tempo is the same, it can be said that the larger the number of sounds contained in the phrase, the more difficult the phrase reproduction task puts a heavy load on the working memory. Also, in general, the task of discerning each sound of a phrase is more difficult when the phrase is presented at a slower tempo than when it is no longer.
The present invention focuses on the "interval or fine pitch (sound interval) of question sound candidates" and "phrase presentation tempo and number of sounds included in the phrase (phrase length)" to perform load control. Make it an issue.

The present invention uses an automatic composition algorithm for forming a phrase as a sound quiz while paying attention to the interval between question sound candidates, the number of sounds included in one phrase, and the phrase presentation tempo as the load applied to the sound quiz. The subject is to propose a new sound-addressing quiz technique including an applied technique and a response means for responding to a fine pitch reproduction task.

In general, a sound quiz is performed by repeating a question, a response, and a judgment.

Generally, there are "single note", "chord" and "phrase" in the question contents of the sound addressing quiz.
When the content of the sound addressing quiz is a single sound, the correctness judgment is made for each sound input.
When the content of the sound addressing quiz is a chord, generally, the input of a plurality of sounds input within a certain time is set as the judgment target, and the correctness judgment is performed in units of a plurality of sounds as chords.
When the question content of the sound addressing quiz is a phrase, generally, the input of a series of a plurality of sounds input within a certain period of time is the judgment target.
However, there may be a note-addressing quiz in which the tonic (tonic) of the chord that is given is answered, or there may be a note-assigning quiz in which only the note name of the first note of the phrase is answered. ..
The habit of giving a short-time sound quiz that fits the practitioner's ability for about 2 minutes in front of fingering practice, etc., may be meaningful in improving the sense of pitch. It is suggested.

The sound addressing quiz system of the present invention
Quiz questioning means (reference sound quiz questioning means, phrase questioning means, candidate sound quiz questioning means),
Quiz response information input means (reference sound quiz response information input means, phrase reproduction information input means, candidate sound quiz response information input means), and correct / incorrect judgment means (reference sound quiz correct / incorrect judgment means, phrase correct / incorrect judgment means, candidate sound quiz correct / incorrect Judgment means),
Is the basic component,
The question questioning means is a question candidate sound determined by the reference sound, a question candidate sound defined by the question range, or a specific question candidate sound set by the user by the reference sound setting means, the question range setting means, or the question candidate sound setting means. Using the information of various question candidate sounds, a phrase consisting of a single note or multiple question candidate sounds is set.
Further, the game control means in the sound addressing quiz system of the present invention updates the value of the number of questions held in the ROM or the like each time a quiz question is given for the number of units (reference sound unit number, phrase unit number), and practices. It is intended to be a means used for game control to adjust the load.

In the present invention, as the task of the sound assignment quiz, the task of causing the user to discriminate the single note given by the system (single note discriminating task), the task of causing the user to reproduce the phrase given by the system (phrase reproduction task), and the single note and the phrase. We deal with such a fine pitch reproduction task. In the single note discrimination task, it is determined whether or not there is an operation of the keyboard or the like corresponding to the questioned sound, and in the phrase reproduction task, it is determined whether or not the same sounds as the sounds included in the questioned phrase are input in the same order. In the fine pitch reproduction task, the fine pitch of a single note input by the user or the fine pitch of each phrase is set as the judgment target.
When the input of a plurality of sounds is to be determined, the input may be accepted at the same time as the question is started by the system, or the input may be accepted after the time when the question is completed.
Regarding the correct / incorrect judgment timing when the question content of the sound address quiz is a phrase, rather than waiting for the user to complete the phrase input, it is preferable to present that the input is incorrect one by one when an incorrect input is detected. , Try to re-present the phrase.

In the following, when expressing a sound in this paper, in addition to the Doremi Fasorashi notation, the note name is described in the manner of, for example, C (60). C (60) refers to the sound of C with note number = 60 in the midi standard.

One aspect of the present invention is characterized in that it has a difficulty level order in which question sound candidates are determined based on a set interval from a reference sound (claim 1).

[Technical significance] It is meaningful to adjust the difficulty level of the sound quiz by deciding the difficulty level order by paying attention to the interval of the question sound candidates and giving the questions corresponding to the order. In addition, it is intended to gradually increase the difficulty level in a quantitative manner by gradually narrowing the interval between question sound candidates for each unit number of questions.

For example, when the number of units is 4, each time a question and a response are made for 4 sounds, if there is a higher order of difficulty, the quiz is continued while changing the order of difficulty to a higher order.
In that case, if the initial difficulty order is the second rank, four single note discrimination tasks were performed in the order of C (60) → C (72) → G (67) → C (72). rear,
Difficulty rank shifts to the third rank and questions continue in the order of C (60) → G (67) → E (64) → C (60), and further the difficulty rank rank shifts to the fourth rank and D ( 62) → F (65) → A (69) → F (65), etc.
Every time a quiz is given to the sound four times, the questions continue while shifting the difficulty order to a higher rank.
Here, the case where the number of units is 4 is illustrated, but the specific value of the number of units is arbitrary. The number of units may be specified by the user.
Further, the difficulty increasing process may be performed only when the user's response content is all correct for the question of the previous unit number, and the difficulty increasing may not be performed when the user's response content includes an incorrect answer.

The settings for the initial difficulty order and the final difficulty order are arbitrary. In other words, in the concrete practice process, it is not always necessary to start the practice from the first rank and practice to the sixth rank.
For example, the practice may be completed when the second rank is started and the fourth rank is completed, or the practice may be completed when the third rank is started and the fifth rank is completed.
In addition, different values may be set individually for the practice length of each difficulty level ranking. For example, the second rank may be carried out once, the third rank may be carried out once, the fourth rank may be carried out twice, and so on.
It is meaningful to make it possible for the user to set the initial difficulty level and the practice length of each difficulty level order using buttons, track bars, and the like. The initial difficulty ranking designation is essential for fitting the load intensity to the practitioner's ability, and the practice length designation for each difficulty ranking ranking is for designing which load level to focus on. Because it is essential.

One aspect of the present invention is characterized in that it has a function of creating a musical phrase by an automatic composition algorithm based on a set question range and setting a phrase reproduction task (claim 2).

[Technical significance] The application of the automatic composition algorithm is meaningful for conducting the sound assignment quiz by the phrase reproduction task.

One aspect of the present invention is characterized in that it has a function of gradually increasing the number of sounds included in a phrase and the presentation tempo thereof in the phrase reproduction task (claim 3).

[Technical significance] Adjust the "phrase length" to control the load on the working memory of the practitioner's brain. Automatic composition technology is applied to gradually increase the number of sounds contained in the phrase to be asked.
It is meaningful to shorten the time required for phrase presentation by increasing the tempo for presenting the phrase (phrase presentation tempo) as the number of sounds contained in the phrase increases.

One aspect of the present invention is characterized by including a layered sound production controller as a quiz response information input means (claim 4, claim 5, claim 6, claim 7).

[Technical significance] The idea of layering the controller and handling parameters larger than the pixel width of the display device is meaningful in responding to the fine pitch reproduction task.

For example, if the pixel width of the display device is 900, the upper limit of the parameters that can be represented by the non-layered trackbar controller is 900, but for example, the width of the first layer is 900 and the width of the second layer is 200. A controller can handle a parameter of 900 x 200 = 180,000, for example, by multiplying two controller values. Furthermore, if only even values are handled, the parameter width is twice that, and if only multiple values of n are handled, the parameter width is n times that. Such a device is meaningful when handling a wide parameter input in the limited size of the display device.

The layered sound production controller in the present invention is a controller in which the width of the first layer is the form width and the width of the second layer is the width of the form or less, assuming that the sound is displayed on a form on a screen having a width. Is intended to be. The layered sound production controller has a function of transmitting a corresponding pitch bend and emitting a sound as the corresponding controller value is changed by an operation.

The present invention has an aspect as a program invention (claim 8, claim 9).

[Technical Significance] The embodiment is a recording medium in which a program or a program for instructing a procedure for causing a system such as a computer or a system having a computer as a component to function as a sound addressing quiz system of the present invention is stored. Is intended.

By adopting the above mechanism, the present invention can quantitatively and finely adjust the load of the sound application quiz. As a result, it becomes possible to carry out a difficulty increasing practice process for the sound addressing quiz. It also stimulates the working memory of the brain, which affects sound, and provides a means to cultivate a sense of pitch that is finer than a semitone.
If it is technically possible to increase the load of the sound quiz in small steps, just as the load of strength training is gradually increased day by day, the sound feeling will be felt by implementing the increasing difficulty practice process. Can be strengthened. As a result of the efforts according to one aspect of the present invention, even if the efforts are made after the age of 30, the sound addressing quiz in which the three sounds of Domiso are used as the discrimination task sound in a state where the reference sound is not shown in advance is provided. Given that it is now possible to answer correctly with 100% accuracy, it is a part of the conventional wisdom that "pitch retention (absolute pitch) as a linguistic element can only be obtained by training for a limited period of time." It is suggested that may have been overturned.

It is a block block diagram which shows the example of the basic structure concerning one aspect of the sound addressing quiz system of this invention. This is an example of the basic flow of a sound addressing quiz system that has a mechanism for increasing the load. It is a figure explaining "the interval of a question sound candidate" as a load about a sound addressing quiz. This is an example of a question in which the intervals between question sound candidates are gradually narrowed. It is a figure explaining the method of setting the question range of a sound addressing quiz by a tonic sound and a root sound. It is a figure explaining the automatic composition algorithm. It is a figure explaining "the number of sounds contained in a phrase" and "phrase presentation tempo" as a load about a sound addressing quiz. It is a figure explaining that a phrase has a repeating structure. It is a figure explaining the question candidate sound setting means and quiz type selection. It is a figure explaining the layered sound production controller.

Hereinafter, each embodiment of the invention will be described in detail based on the drawings.

FIG. 1 is a block configuration diagram showing an example of a basic configuration according to one aspect of the sound addressing quiz system of the present invention. The ROM stores a control scenario that outputs video, sound, etc. to the output device while the CPU updates each parameter stored in the RAM, and random information used for control. Furthermore, it has a mechanism to detect the input from the input device.

The present invention is basically intended to operate on a PC, but for example, a person, a timekeeping device, a memorandum, etc. are responsible for the action of an electronic device such as a CPU or ROM, and a piano is based on a controlled scenario. It does not interfere with the system mode such as being sounded. In addition, various changes such as combining a plurality of machines and allocating and implementing functions to each hardware component can be easily assumed, and these changes are naturally included in the idea of the present invention. It is a concept to be done.

FIG. 2 is an example of a load increasing mechanism and a basic flow thereof according to one aspect of the sound addressing quiz system of the present invention.
After the start is decided, the structure is such that the question is asked, the reproduction response is relied on the memory, the check is made, the correct / incorrect confirmation is displayed, and the difficulty level is gradually increased if the answer is correct a certain number of times.

When the question of the single note discrimination task or the single note fine pitch reproduction task starts, the question sound selected by the quiz questioning means starts to sound from the question candidate sounds using random numbers or the like.
When the question sound is a decaying sound, preferably, the quiz questioning means keeps sounding so as to repeatedly hit the sound at intervals of about 500 ms.

When the question of the phrase discrimination task or the phrase fine pitch reproduction task starts, each sound of the phrase created by the phrase questioning means starts to sound at a constant tempo (phrase presentation tempo).
When all the sounds of the phrase have been played, after a waiting time of the same length as the phrase was played, the phrase questioning means again plays each sound of the phrase from the beginning of the phrase.
If there is an error in the input content from the user, a warning sound such as a buzzer indicating that the answer is incorrect is sounded, the phrase performance is stopped if the phrase is being played, and the phrase is started from the beginning. Play each sound.

If the quiz response information entered by the user matches the question content, the correct answer is processed, and if they do not match, the incorrect answer is processed.
When the answer is correct, the note given on the score on the screen and the mark indicating that the answer is correct may be displayed for a certain period of time of about 800 ms, and then the next question may be given. It should be noted that this 800 ms is an example, and it does not prevent the device such as how long the correct answer is displayed as one sound of the phrase presentation tempo.
The content and display format of the mark may be any one, such as a plosive animation or an arrow piercing animation.
If the content of the question is a phrase, the result will be displayed on a phrase-by-phrase basis. That is, for example, at the end of input when the answer is correct, the constituent sounds of a series of phrases and the mark indicating that the answer is correct are displayed side by side for a certain period of time.

In the example of FIG. 2, when the number of units (reference sound unit number, phrase unit number) is correct, that is, the number of questions (= number of correct answers) ≥ unit number, the number of questions is reset to the next. The mechanism to proceed to the question of the difficulty level of is shown.
This is based on the basic idea of gradually increasing the practice load while encouraging the practitioner to adapt to the high load.
For example, the correct answer rate may be considered as a criterion for determining whether or not adaptation has been obtained, and whether or not brain activity related to absolute pitch appears by checking the activation status of, for example, the dorsolateral posterior part of the left frontal lobe. Is checked, and the load control feedback may be performed in such a manner that the load is gradually increased only when the adaptation is obtained.
In addition, the number of units basically means the number of times that the question of the sound quiz → response → judgment is repeated until the difficulty level is changed, but the response is incorrect as in this example. It has an aspect as an upper limit of the number of questions that can be scheduled to be decremented in some cases.

In one aspect of the sound addressing quiz system of the present invention, candidates for problem sounds are determined as shown in FIGS. 3 (a) to 3 (e) based on the reference sound set by the user. FIG. 3 illustrates the candidate sound of the problem sound in each difficulty order when the reference sound is do.

It can be said that the quiz load is heavier when the interval between each question sound candidate sound is narrower.
For example, the task of discriminating domiso (see Fig. 3 (c)) is more difficult than the task of discriminating the sound of octave differences (see Fig. 3 (a)).
The task of discriminating doremifasolaside (see FIG. 3 (d)) is more difficult than the task of discriminating domiso (see FIG. 3 (c)).
Further, the task of discriminating a chromatone containing a black key (see FIG. 3 (e)) is more difficult than the task of discriminating doremifasolaside (see FIG. 3 (d)).
The magnitude relationship of difficulty is generally determined by octave discrimination (see Fig. 3 (a)) <dosodo discrimination (see Fig. 3 (b)) <domiso discrimination (see Fig. 3 (c)) <doremi fasolaside discrimination (see Fig. 3 (d)). ) <Chromatone discrimination (see FIG. 3 (e)).

It is advisable to use, for example, a random number stored in the ROM to determine which of the question sound candidates is specifically selected by the questioning means. An arbitrary automatic composition algorithm may be applied to determine the order of questions.
When there are three candidate sounds for questions, it is preferable to apply a questioning algorithm that asks a sound different from the sound that was asked immediately before, but when the number of candidate sounds for questions is sufficiently large, various questioning algorithms are applied. Is possible.
FIG. 3 (d) corresponds to the Doremi Fasolaside discrimination task (fifth rank of the difficulty order in claim 1), but all the sounds of the natural major scale are included in the question candidates as in the fifth rank. In that case, it is preferable to apply an automatic composition algorithm to set a natural musical pattern.
FIG. 3 (e) corresponds to the chromatone discrimination task (sixth rank of the difficulty order in claim 1), but this may be further subdivided. In other words, for example, the questions for the chromatone discrimination task are devised to change the questioning method, such as (1) a pattern that includes a chromatic scale as a transitional sound created by the automatic composition algorithm, and (2) a pattern in which chromatones are randomly arranged. It is possible to subdivide the difficulty level according to. In general, it is more difficult to give a quiz to a sound in a question pattern without a key than in a pattern in which a phrase with a key is given. In addition, if a sound that is half a note higher than the previous sound or a sound that is a half tone lower than the previous sound can be asked, the question for that sound (adjacent movement) is repeated about 4 times, and the next question is 4 to 6 than the previous sound. If a sound that is half a tone away from the question can be asked, that sound will be asked (jump), and if a sound that is half a note higher than the previous sound or a sound that is a half tone lower than the previous sound can be asked, that sound will be asked (jump). It is also meaningful to apply the questioning method that combines the adjacent movement and the jump in such a way that the adjacent movement) is repeated about 4 times. Anyway, it is possible to create various question patterns by increasing the number of question candidate sounds, but the application or combined use of these question pattern creation methods is not hindered.

FIG. 4 shows an example in which the difficulty level gradually increases as the questions progress.
The first bar of the score is octave discriminant,
The second measure is a dosodo discrimination task,
The third measure is the Domiso discrimination task,
The fourth measure is a discriminant task for sounds excluding domiso from the natural major scale.
The 5th and 6th measures are the Doremi Fasolaside discrimination task,
The 7th and 8th measures are the chromatone discrimination tasks,
Is being asked.
As the questions progress in this way, it is conceivable to move up the difficulty level and gradually narrow the intervals between the question sound candidates.

Here, the case where the number of reference note units is 4 is illustrated, but the specific value of the number of single reference note positions is arbitrary. The user may be able to specify an arbitrary value for the number of reference sound units.
In addition, it is arbitrary from which difficulty order the questions are started and to which difficulty order the questions are given. In addition, the question length design in each difficulty level is also arbitrary.
For example, the practice may be completed when the second rank is started and the fourth rank is completed, or the practice may be completed when the third rank is started and the fifth rank is completed. Different values may be set individually for the practice length of each difficulty ranking. For example, the second rank may be asked once for the number of reference sound units, the third rank may be asked once, the fourth rank may be asked twice, and so on.
It is meaningful to make it possible for the user to set the practice length of the initial difficulty level and each difficulty level order by using buttons, track bars, etc., and the system has a start level setting means and a practice length setting means. Not disturbed.
Further, after the question of the chromatone discrimination task is given, the question may be shifted to the question of the fine pitch reproduction task, and the permissible range of the fine pitch reproduction task may be further narrowed.

FIG. 5 shows an example of a reference sound (tonic and root) and a corresponding question range. In this example, the tonic is C, and the basic question range is shown for each of the seven types of routes from C (60) to B (71).
As in this example, the question range is basically "7 notes in one octave with the root note as the second note on the natural major scale of the tonic key". Of course, when the tonic is a sound other than C, the question range can be determined in the same way. In the example, the natural major scale is adopted, but the type of scale adopted is arbitrary. The above-mentioned question range setting method is mainly for the convenience of giving a clear question range to the question processing using a machine.
The method of specifying the tonic and route is arbitrary. You may be able to specify the value in the track bar on the form that accepts numerical input, or you may be able to enter the numerical value in the text box. In response to the value input operation, the question range corresponding to the input value may be displayed on the form for easy visual inspection.

FIG. 6 shows an example of an automatic composition algorithm. Automatic composition technology makes it possible to obtain an inexhaustible number of musical phrases of any length with automatic composition.

For example, assuming that the key is C major (that is, the tonic is C), the scale of the sounds of Doremi Fasorashi is arranged in this order, and the first chord is C major, (1-1) of the option example in Fig. 6 If -1), (2-1), (3-1-1), (2-14), (3-2-1) are selected, a musical pattern called "Domidsodofasora" is created. To. In other words, in (1-1-1), if the key is C major for chord progression I → IV, the chord progression is C major → F major. If the constituent sounds of I: C major (domiso) are (2-1) 1,3,5, the constituent sounds are do, mi, and so, and the arrangement is (3-1-1) 1 → 2 → 1 →. In the case of 3, the created pattern is do-> mi-> do-> so. Furthermore, in (1-1-1), the next chord is IV: F major (farad), but if the constituent notes are (2-14) 1,2,3,5, the constituent notes are fa, so, la. , Do, and if they are arranged in ascending order within the assumed scale, they become do, fa, so, and la. If the arrangement is (3-2-1) 1 → 2 → 3 → 4, the created pattern will be do → fa → so → la, and the above “domidoso” and “dofasora” will be connected to each other. "Dofasora" is the output content.

Since the musical pattern obtained in this way has a tonality corresponding to each chord of origin, it fits the chord attached from the constituent notes of the chord (for example, in the above example, Domidoso fits the chord of Domiso). , Dofasora should fit the farad chords). That is, the idea illustrated in FIG. 6 can be used as a basis for creating a musical pattern with an idea of chord progression. This makes it possible to obtain an inexhaustible number of musical phrases of any length. In addition, in the sound addressing quiz that asks a phrase, it is possible to present the phrases that follow the phrase that was given earlier one after another. In addition, by prepending the sound training by the sound addressing quiz system of the present invention to the reading practice and fingering practice in which the question range and the automatic generation mechanism of the musical pattern are common and consistent, the sound feeling is well activated. It is noteworthy and significant that the entire practice process can be carried out while in the state of being.

FIG. 7 shows an example of a question in which the phrase presentation tempo is gradually increased for each question in the phrase reproduction task.
For example, the tempo increases by 1 for each question, and the phrase length increases by 1 for every 20 tempos.
The algorithm for adjusting the length of the phrase illustrated here is the number of sounds contained in the phrase = Int (phrase presentation tempo / 20)
That is.
Note that this is an example. For example, the tempo may be increased by 2 for each question, and the phrase length may be increased by 1 for every 10 increase in tempo.

The phrase reproduction task may be accepted from the user at the same time as the question is started, or may be accepted after the question is completed.
Regarding the correct / incorrect judgment timing in the case of the phrase reproduction task, if the user's input of the phrase reproduces the content of the question, it is sufficient to determine that the answer is correct when the phrase input is completed and proceed to the next step. However, it does not necessarily wait for the user to complete the phrase input, but preferably, when an erroneous input is detected, it is presented that the input is incorrect and the phrase is re-presented.

As illustrated in FIG. 8, when the number of sounds included in the phrase is 8 or more, the repeating structure may be set. In that case, for example, make sure that one phrase contains the same four sounds.
Note that the number 8 for the number of sounds included in this phrase and the number 4 for the repeating structure are examples, and this may be 6 or 3. In other words, for example, when the number of sounds contained in a phrase is 6 or more, a repeating structure consisting of 3 sounds may appear. Generally, when the length of the repeating structure is n, the appearance of the repeating structure is allowed when the number of sounds included in the phrase is 2n or more. Note that n is an arbitrary natural number of 2 or more.

FIG. 9 shows an example of a form having a keyboard portion and an operation button portion and displayed on a display as an example of the question candidate sound setting means.
In the example of this figure, a message prompting the selection of three or more sounds is displayed at the upper part of the button portion, but the form may have such a message display portion.
In this example, a mechanism is planned in which a question candidate sound is selected by clicking or tapping a keyboard, and deselected by clicking or tapping an already specified keyboard again. It is preferable to perform drawing processing such as filling on the specified keyboard so that the selected state is easy to understand.
When three or more question candidate sounds are selected and the button in the operation button part is pressed, a sound addressing quiz for the selected question candidate sounds starts.
When you press the button corresponding to the "fine pitch reproduction task" in the operation button part (the fineT button is intended to be that button in the figure), the screen is switched and the sound addressing quiz system of the present invention is layered. The question of "Fine pitch reproduction task" that uses the sound production controller for the response begins, but it is not prevented that the buttons corresponding to various practice menus coexist in this operation button part. For example, a type of "a very simple note discrimination task that asks a question candidate sound" that responds using a keyboard instead of a layered sound creation controller, or a natural major scale Doremifa that uses the selected question candidate sound as a tonic. It is meaningful to present a plurality of consecutive scales composed of soracids and to have a menu such as "the task of discriminating the do (tonic sound) of the sound of Doremifa soracid".

Regarding the sound addressing quiz of the method of responding to a fine pitch, a method of responding by an input means like a musical instrument is preferable to a method of answering selectively from an input means like a piano keyboard. By using a controller that is layered for rough pitch and fine pitch as to how to make the fine pitch respond, it is possible to avoid restrictions due to the size of the display input device. This device is meaningful because it enables parameter transmission or fine pitch response with a wide range even with a small device.

FIG. 10 is a diagram illustrating a mechanism of fine pitch response by a layered sound production controller for responding to a fine pitch reproduction task.
Here, an example of performing a fine pitch response by a mechanism that emits a sound obtained by adding a pitch change to note information by pitch bend transmission of the midi standard will be described.
The pitch bend range value and the basic note value are set so that all the question candidate sounds are included in the range between the highest note and the lowest note that can be produced by the basic note and the pitch bend range. For example, the note located between the lowest note and the highest note among the question candidate sounds may be used as the basic note, and the pitch bend range corresponding to the difference between the lowest note and the highest note may be set. The pitch bend range may be set to a slightly larger value with some allowance.

The sound production controller of the first layer is displayed on the form as shown in FIG. 10A, and can be dragged left and right within the range of the form width (strictly speaking, the width obtained by subtracting the width of the knob from the form width).
Since the range of the pitch bend value in the midi standard is -8192 to +8191, the pitch bend value at the time of operating the sound production controller of the first layer is -8192 + 16384 ÷ form width × the position of the sound production controller of the first layer. In this case, the value of the sound production controller position in the first layer is 0 when the knob is at the left end position of the form, and the form width (strictly speaking, the value of the knob width from the value of the form width) when it is at the right end position of the form. The value obtained by subtracting).

When the drag of the sound production controller of the first layer is released, the sound production controller of the second layer is displayed on the form as shown in FIG. 10 (b). Preferably, basically, the sound sound controller of the second layer is displayed so that the position of the knob of the sound controller of the first layer separated from the drag is around the center of the width of the sound controller of the second layer. The sound production controller of the second layer can be dragged left and right with the position of the knob of the sound production controller of the first layer as the center. The value of the sound production controller position in the second layer is 0 in the center of the track bar, a negative value on the left, and a positive value on the right.
The pitch bend value at the time of operating the sound production controller of the second layer is, for example, "the pitch bend value at the time of operating the sound production controller of the first layer + the value of the sound production controller position of the second layer". In this way, it is intended that the fine pitch is specified by the sound production controller of the second layer and used for the sound addressing quiz.

While dragging each controller, it emits a sound corresponding to the sound of the basic note changed by pitch bend.
When you press OK, the content of the sound becomes the input content (quiz response information) to be judged as correct / incorrect, the display of the sound production controller of the second layer is turned off, and only the sound production controller of the first layer is drawn on the form. It is assumed that it is in the state of being. The correctness judgment of the fine pitch reproduction task is performed with an allowable range. It can be said that the narrower the allowable range, the more difficult it is. The permissible range should be within ± 10 cents of the reproduction task sound.
For example, in the case of a single note fine pitch reproduction task with C (60) as the question sound, if the pitch of the input content is 5 cents lower than C (60), "C (60) -5 cent" as shown in Fig. (B). Is displayed, and if it is within the set allowable range, a mark indicating that the answer is correct may be displayed as shown in Fig. (B). It may be possible to list the results of a series of exercises.
In the case of a phrase fine pitch reproduction task, the result is displayed in phrase units. In other words, at the end of input when the answer is correct, the constituent notes of a series of phrases and the mark indicating that the answer is correct are displayed side by side, and for each constituent note, the procedure is the same as for the single note fine pitch reproduction task. The input contents and differences corresponding to each note may be displayed at the bottom of the note.
