Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a music performance device, and more particularly, to a music performance device that generates musical tones of a corresponding scale in response to lyrics input of a selected song. .

[Prior Art] Traditionally, for beginners to learn to play a musical instrument,
Learned from teachers in the field, such as at school or private tutoring,
It was common for students to practice what they had been taught over and over again.

[Problems with the conventional technology] However, except in special cases, there is a limit to the amount of time students can learn from their teachers, and students practice repeatedly on their own while remembering what they have been taught, but the content that they thought they had memorized is not as good. Often ambiguous;
The results of my review did not improve as much.

[Purpose of the Invention] The present invention has been made to solve the above-mentioned inconveniences.The purpose of the present invention is to provide a simple and easy-to-use method that allows anyone to confirm the correct pitch corresponding to the lyrics during self-study or review of musical instrument performance. To provide a music performance device by inputting lyrics.

[Summary of the Invention] The present invention provides that each time a lyric means among a plurality of lyrics specifying means is operated, lyric data indicating the lyrics specified by the operation is arranged in accordance with the order of a series of lyrics constituting a song. , compares whether or not they match with the lyrics data stored in the storage means, and each time these lyrics data match each other, the pitch is determined based on the pitch data corresponding to the lyrics data related to the match. A musical tone having a pitch corresponding to the data, for a tone length corresponding to the tone length data related to the pitch data,
The key point is that they occur sequentially.

[Example] Hereinafter, one example of the present invention will be described in detail. Referring first to FIG. 1, which shows a schematic block diagram of the music performance apparatus of this embodiment, reference numeral 10
is a keyboard, and its panel surface consists of a numeric keypad system, with a song selection key group 11 for inputting an arbitrary number to select the desired song, and a 50-tone key group 12 representing Japanese characters in hiragana. and is provided. Each key in the 50-tone key group 12 is assigned a clearly distinguishable character code, and these character codes are sent to the control circuit 14 and the coincidence detection circuit 15 in response to key operations.

The ROM pack 16 is a read-only memory that stores a plurality of songs in advance and outputs a series of lyrics data in response to song address data from the control circuit 14. RAM1 via interface circuit 17
8. The RAM 18 is a random access memory that temporarily stores a series of read lyric data.
The signals are sent one by one to the control circuit 14 and the coincidence detection circuit 15. The match detection circuit 15 compares the character code corresponding to the key selected in the 50-tone key group 12 with the lyrics code (described in detail later in connection with FIG. 2) of the lyrics data, and compares the character code corresponding to the key selected in the 50-note key group 12 and determines whether the character code corresponds to the key selected in the 50-note key group 12 and the lyrics code (described in detail later in connection with FIG. 2). A result match signal is output to the control circuit 14. In response to the match signal from the match detection circuit 15, the control circuit 14 outputs pitch codes and length codes forming the received lyrics data to the tone generator 19. Therefore, the tone generator 19 generates a musical tone signal of a corresponding scale from the received lyric data and a corresponding tone duration, and emits the sound through the speaker 20. Note that data reading from the RAM 18 or writing is performed by a read/write signal R/W from the write control circuit 14.

Now, a series of lyrics data stored in the ROM pack 16 will be explained with reference to FIG. 2, taking, for example, the song "Rabbit" shown in FIG. 3 as an example. As you can see from the figure, the lyric data for the lyric “u” shown at the top is 50.
A lyric code that substantially corresponds to the letter code assigned to the key "U" in tone key group 12, a pitch code of F4 indicating the octave and scale, and a quarter note indicating the length of the note. It consists of three chords, including the note length chord. Similarly, the lyric code for the third lyric "gi" consists of the lyric code corresponding to the letter code "ki", the pitch code of A4, and the pitch code of eighth note. Each lyric code is used for lyric determination in the match detection circuit 15. Furthermore, as shown above, in the lyrics, for example, a voiced sound such as "gi" or "zu" is treated as "ki" or "su" for convenience.

Next, a series of operations will be explained in detail. Here, we will select the song “Usagi” and use the lyrics “u”, “sa”,
Assume that a scale note corresponding to "gi" is emitted.

The operator first specifies the code number corresponding to the song "Rabbit" using the song designation key group 11, confirms the entered code number through the display section (not shown), and then presses the input key. Then, the code number is given to the control circuit 14, and the control circuit 14 gives the read address data of the song corresponding to this code number to the ROM pack 16 via the interface circuit 17.
A series of lyric data shown in FIG. 2 from the ROM pack 16 is passed through the interface circuit 17.
Stored in RAM18.

At this point, the lyrics data stored in the RAM 18 is waiting for the operator to operate the 50-tone key group 12, and the lyrics data corresponding to the first lyric "u" in the RAM 18 is controlled as address "0". read out by the circuit 14;
It is applied to the control circuit 14 and the coincidence detection circuit 15.

Here, when the operator operates one key in the 50-tone key group 12, the character code corresponding to that key is sent to the match detection circuit 15, and it is determined whether it matches the lyrics code. If they match, a match signal is output, but if they do not match, the operator is requested to operate the correct key again.

If the correct key "U" is pressed and the control circuit 14 receives a matching signal, the first lyrics data corresponding to the lyrics "U" is taken into the control circuit 14, and the tone generator 19 generates the pitch F4. A musical tone is generated for a quarter note time and is emitted from a speaker 20. At this time, an address counter (not shown) provided in the control circuit 14
is incremented when the lyrics data is imported, and the lyrics address data is set to 1 and RAM1 is
8. Therefore, the RAM 18 outputs the next lyric data corresponding to the second lyric "sa".

Next, when the key "sa" is pressed and the control circuit 14 receives a matching signal, the lyric data of "sa" is taken in and transmitted through the tone generator 19 and speaker 20 to the musical tone F4 corresponding to "sa". is played as an eighth note. In the control circuit 14, the address counter is further incremented. Therefore, RAM
The lyrics address data for No. 18 becomes "2", and the RAM 18 outputs the lyrics data corresponding to the third lyrics "gi" as the first data there. This lyrics data is transmitted through the same processing steps as before by the operator's subsequent operation of the key "ki", and is outputted from the speaker 20 as the musical tone A4 of "gi".
A diacritic sound is emitted. The lyrics of the songs selected in this way are sequentially emitted as musical tones with accurate pitches and durations in response to key operations in the correct order by the operator.

The above explanation is based on drawings that extract the main parts of the music performance device by inputting lyrics of the present invention, and has been made only in relation to its important functions. , ROM pack replacement, automatic playback of selected songs,
It may also have a function such as checking the pitch of each lyric (the sound continues to be emitted while the key is pressed).

Further, the keys for inputting and specifying lyrics may include not only the 50 syllables but also voiced sounds, semi-voiced sounds, etc., or English letters. Also,
When multiple characters such as "ju" correspond to one musical note, the corresponding scale note may be generated by specifying the first character "shi" or "ji".

[Effects of the Invention] As is clear from the above description, according to the present invention, each time the lyrics specifying means among the plurality of lyrics specifying means is operated, the lyrics data indicating the lyrics specified by the operation are In accordance with the order of a series of lyrics constituting a song, each time a match occurs with the lyrics data stored in the storage means, a sound corresponding to the pitch data is generated based on the pitch data corresponding to the lyrics data related to the match. Since musical tones with high pitches are generated sequentially for the duration corresponding to the duration data related to the pitch data, the series of pitches (scales) and durations that make up the piece of music are (note length), even if you don't remember them clearly, it's easier to remember the pitch (scale) and length (note length) of a series of lyrics. By sequentially operating the lyrics specifying means of the lyrics specifying means, musical tones having a series of pitches can be sequentially generated for corresponding tone lengths. Therefore, even if a song is composed of complex pitches (scales) and durations (note lengths), if you know the series of lyrics that make up the song in order, you can understand the series. By simply operating the lyrics specifying means in accordance with the order of the lyrics, musical tones having complex pitches corresponding to the series of lyrics can be generated and played for the corresponding duration.

Further, each time the lyrics data indicating the lyrics specified by the operated lyrics specifying means matches the lyrics data stored in the storage means in accordance with the order of a series of lyrics composing the song, the lyrics related to the match are performed. Based on pitch data corresponding to the data, a musical tone having a pitch corresponding to the pitch data is generated for a duration corresponding to pitch data related to the pitch data. . In other words, if the respective lyrics data do not match each other, a musical tone having a pitch corresponding to the lyrics data indicating the lyrics specified by the operated specific lyrics specifying means is set to correspond to the tone length data related to the pitch data. The configuration is such that the sound is not emitted for a long period of time. Therefore, scale learning can be performed while correlating a series of lyrics and a corresponding series of pitches and lengths with each other in the state in which musical tones are generated.
