Description

[Detailed description of the invention]

The present invention makes it easy to create notes that make up complex scales and chords.
The present invention relates to a device for displaying constituent notes of scales and chords that can be displayed quickly. As is well known, in composing music, it is extremely important and indispensable to understand the constituent notes of all kinds of scales and chords, but until now there has been no equipment that can instantly grasp the constituent notes of complex scales and chords. Not,
I was relying on my memorization skills. Therefore, the present invention has made it possible to display the constituent notes of more than 1,000 types of scales and chords in patterns smaller than 1/10 by converting notes into numbers and using the addition method made possible by this. The purpose is to provide a display device for the constituent notes of scales and chords. First, a method for finding constituent notes of a scale and chord according to the present invention will be explained. (1) Scale As shown in Table 1, note C (British and American note names, same below) is set as 0, and each note is replaced with a number, increasing by 1 for each semitone. Convert sounds into numbers.

[Table] By the way, the scale of C major is
It is made up of the sounds C, D, E, F, G, A, and B, but when converted into numbers using Table 1, they become 0, 2, 4, 5, 7, 9, and 11. Similarly, the scale of D major is D,
Since they are E, F#, G, A, B, C#, they can be rewritten as 2, 4, 6, 7, 9, 11, 13 from "Table 1". In this way, from C major to B
If we digitize the constituent notes of the 12 scales up to the major, and write them down as a sequence of numbers, we get the table below.

[Table] From the above, a numerical sequence consisting of the seven constituent tones of a certain scale can be created by adding a number indicating the tonic of the scale (2 for a D major) to each number (2) of the digitized constituent tones of a C major. 0, 2,
4, 5, 7, 9, 11). In other words, if you want to know the constituent notes of a desired key, add the number indicating the tonic of that key to each number of the constituent notes of the C major, and you will find the constituent notes of the desired key. Obtained numerically. For example, if you want to know the constituent notes of the A ^b major (A flat major) scale, you can change the number 8 representing the tonic A ^b to the C major 0, 2, 4, 5, etc.
Just create a sequence of numbers by adding them to the sequence of numbers 7, 9, and 11. Therefore, A ^b measure is 8, 10, 12, 13,
15, 17, 19. Finally, each numbered sound is given a note name (C, D, E,
F, G, A, B and #, b), the above A ^b measure becomes A ^b , B ^b , C, D ^b .
We can obtain the constituent tones of the scale E ^b .
However, when writing this on a musical score, the A ^b major is a tone symbol of the b system, so if it is enharmonic, such as A ^b and G#, it should be written as the note name of the b system, such as A ^b or D. You will have to choose ^b etc. As mentioned above, in the major scale, if you create one pattern of 0, 2, 4, 5, 7, 9, 11, which is the sequence of C major, all the constituent notes of the major scale can be displayed by addition. It will become. The above idea can also be applied to the case of minor scales (3 types). Similarly to the above, if we convert the scale of the minor key with C as the tonic, that is, the scale of C minor (C minor), we have the following: Natural minor scale: 0, 2, 3, 5, 7, 8, 10 Harmonic minor scale: 0, 2, 3, 5, 7, 8, 11 Melodic minor scale: 0, 2, 3, 5, 7, 9, 11 (ascending) Here, for example, the constituent notes of the natural minor scale of G minor (G minor) If you want to know, the tonic note is 7, so the sequence 7, 9, 10 is obtained by adding 7 to the sequence C minor (natural minor scale) 0, 2, 3, 5, 7, 8, 10. 12, 14, 15, 17
is the sequence of tones that make up G minor. And the above numerical 7, 9, 10,
By converting 12, 14, 15, and 17 into their corresponding pitch names and displaying them, the constituent tones of G minor, G, A, B ^b , C, D, E ^b , and F, are obtained. Note that G minor is a b-type tone symbol, so when writing it on the score, choose B ^b and E ^b . Hereinafter, in the case of a harmonic minor scale and a melodic minor scale, constituent tones of a desired key can be obtained in the same manner. To summarize the descriptions so far, first, when the C note is the tonic, the constituent notes of the major scale, natural minor scale, harmonic minor scale, and melodic minor scale are digitized and used as constants for each scale ( (See Table 2).

[Table] If you want to know the constituent notes of a scale in a desired key, add the number indicating the tonic of that key to each number of the constant of the scale to which it belongs, and the constituent notes of the scale in the desired key can be found. Obtained numerically. Then, by converting each of the above numbers into the corresponding note name, the constituent notes of the scale of the desired key can be obtained. (2) Code Names The same concept as in the case of scales in (1) above can be applied to code names as well. That is, as shown in Table 3, the constituent tones of all chord types (minor chord, seventh chord, etc.) when the C note is the root note are digitized and considered as constants for each chord type.

【table】

[Table] Here, let us assume that the desired chord name is M. To obtain the constituent notes of M, add the number indicating the root note of that M to each number of the constant of the chord type to which M belongs. Then, the constituent sounds of the desired code name M can be obtained as numbers. Hereinafter, as in (1) above, by converting each number into a corresponding note name, the constituent notes of the desired chord name can be obtained. For example, if you want to know the constituent notes of the chord name Fm ₇ , you can change the number 5 representing the root note of Fm ₇ to the constants 0, 3, 7, 10 of the chord type m ₇ (minor seventh) from Table 3. If you add them to each number, the constituent notes of Fm ₇ will be converted into numbers 5, 8, 12, and 15. Then, by converting each number into a pitch name, the constituent tones of Fm ₇ , F, A ^b , C, and E ^b , are obtained. Note that the minor seventh is a b-based chord, so if the note is enharmonic, choose the note name with b. (3) Diatonic chords Convert all diatonic chord constituent notes (3 x 7 = 21 types) from major scale, natural minor scale, and harmonic minor scale to numbers (3 x 7 = 21 types) when the C note is the tonic. Considered as a constant for each diatonic code (see Table 4)

【table】

[Table] If you want to know the diatonic chord of a desired key, enter the number indicating the tonic of that key.
After adding the numbers to the constants of each diatonic chord, each added number is converted into a corresponding note name to obtain the constituent notes of the desired diatonic chord. For example, if you want to know the chord of F major, add the number 5, which indicates the tonic of F major, to the constants 4, 7, and 11 of the major scale from Table 4. You will get the number 16, which you can convert to a pitch name. (4) Surrogate chord T (tonic), S when C is the tonic
(subdominant), Sm (subdominant minor), D (dominant) and their substitute chords are converted into numbers and their respective constants are considered (see Table 5).

[Table] If you want to know the constituent notes of a substitute chord in a desired key, enter the number indicating the tonic of that key.
By adding the numbers to the constants of each proxy chord and converting them into pitch names, the constituent notes of the proxy chord in the desired key can be obtained. For example, if we consider m ₇ , which is the most well-known S surrogate code, as an E ^b major,
It can be found as follows. In other words, the number 5 indicates the tonic E ^b of E ^b major.
are added to the respective numbers of the constants 2, 5, 9, and 12 of m7 from Table ₅ to obtain the numbers 5, 8, 12, and 15, and when these numbers are converted into pitch names, F, A ^b ,
We obtain the component sounds of m ₇ , which is the S substitute chord of E ^b major, C and E ^b . Next, a scale and chord constituent note display device according to the present invention will be described with reference to the drawings. First, in the figure, reference numeral 1 is a switch for indicating the tonic/root note, which is a switch with the note names of C, D, E, F, G, A, and B written on it, and when the switch is pressed (closed), The numbers replaced as shown above, ie, 0, 2, 4, 5, 7, 9, and 11, are sent out. 2 is a # switch, and 3 is a b switch. When # switch 2 is pressed, +1 is sent out, and when the b switch is pushed, -1 is sent out. 4 is encoder, 5
is a register, 6 is a scale instruction switch, 7 is a chord type instruction switch, 8 is a diatonic chord instruction switch, and 9 is a substitute chord instruction switch. When these switches are pressed, the constant generator of the constituent notes is activated. 10, constants such as those shown in "Table 2", "Table 3", "Table 4", and "Table 5" are sent out. 11 is an accumulator, 12 is a converter, and 13 is a keyboard type display device. The display device 13 converts substituted numbers into pitch names and displays them. This is done by lighting a lamp 13a. It may be configured such that the sound of the corresponding note name is also output at the same time as the is lit. However, in the case of a chord, the sounds are played simultaneously, but in the case of a scale, the sounds are designed to be played sequentially. The display operation of each constituent sound will be described below. (1) When displaying the constituent notes of a scale, (a) C, D,
When you press the switch indicating the tonic of the desired key from E, F, G, A, B, the number corresponding to the switch (0, 2, 4, 5, 7,
9 or 11) is converted into a binary number by the encoder 4 and set in the register 5. However, if the tonic is a note name with # or b, the contents of register 5 will change to +1 or - by next pressing # switch 2 or b switch 3.
1 will be given. This also applies to other constituent sounds described later. For example, in the case of E ^b major (E flat key), to set the tonic E ^b in register 5, first press the E switch of tonic/root indication switch 1, and set the corresponding number "4" to E. is converted into a binary number by the encoder 4 and set in the register 5. Next, when b switch 3 is pressed, the contents of register 5 are incremented by 1, and "4-1=
3” becomes the contents of register 5. (b) When any one of the major scale, natural minor scale, harmonic minor scale, and melodic minor scale (upward row) in the scale instruction switch 6 is pressed, the corresponding constant (Table 2) is set in the accumulator 11. For example, in E ^b major, when you press the major scale switch, the major scale constants ``0, 2,
4, 5, 7, 9, 11” is the accumulator 11
It is set to . (c) Next, the contents of the register 5 are added to the contents of the accumulator 11 to each digit, and the contents are set in the accumulator 11 again. The contents of this accumulator 11 are converted by the converter 12 to the corresponding position of the display 13, and the lamp 13a at the position is converted.
lights up. That is, if the content of the accumulator 11 is "0", the lamp on the C symbol of the display 13 is activated, if it is "1", the lamp on the C#, D ^b symbol is activated, and if it is "2", the lamp on the D symbol is activated. , and if it is "35", the lamp at the B symbol will be lit. Therefore, in the E ^b measure example from earlier, the content 3 of register 5 is added to each digit of the content 0, 2, 4, 5, 7, 9, 11 set in accumulator 11. Then, 3, 5, 7, 8, 10, 12, and 14 are set in the accumulator 11 again. Then, the contents of this accumulator 11 are converted into corresponding lamp positions on the display 13 by the converter 12, and are converted into the corresponding lamp positions of 3, 5, 7, 8, etc.
Lamps 13a at positions corresponding to 10, 12, and 14,
That is, the lamps 13a located at positions E ^b , F, G, A ^b , B ^b , C, and D are turned on. (2) When displaying the constituent notes of a chord name (a) As in the case of (1), use the C, D, E, F, G, A, B switch of tonic/root note indicating switch 1. A number indicating the root note of the desired chord name is converted into a binary number by an encoder 4 and set in a register 5. (b) Press switch 7 for chord type indication such as +5 (augment) or 7 (seventh) and set the corresponding constant (Table 3) in accumulator 11.
Set to . (c) Perform the same operations as (c) for the scale in (1) (excluding the example). (3) When displaying diatonic chord constituent notes (a) Perform the same operation as (b) for the scale (1), but
Excluding examples. (b) Press one of the diatonic instruction switches 8 indicating the chords , , , , , and set the corresponding constant (Table 4) in the accumulator 11 . (c) Below, perform the same operation as (c) in the scale (1). (4) When displaying the constituent notes of a substitute chord (a) Perform the same operations as (a) for the scale in (1), except for the example. (b) Press the switch 9 for instructing T, S, Sm, D and any of these proxy codes to set the corresponding constant (Table 5) in the accumulator 11. (C) The following is the same as (C) in the scale (1). As explained above, the present invention can display a desired constituent note by simple addition and switch operations, so it facilitates the use of scales and chords, which were not generally used due to their complex tonal structure. By using substitute chords, anyone can easily add a variety of accompaniment chords to a melody.
