When a temporary table is attached, the user first selects the temporary table selection switch 18, recognizes the pressed pitch and selects the next beat. In the case of a comma, the user directly presses the comma switch 20 and determines the time signature as the beat selection switch 21.

After editing, if you select the score type and number with the score number selection switch (23), it is saved with the corresponding name.

If you want to play it, you can change it to play mode and select the type and number of the score. At this time, if you want to play chord accompaniment, you can set it to duet mode. For example, if B1 is a song edited with the accompaniment music of A1, select 'A1, B1'.

However, in the case of inputting only the melody by the musical note without inputting the time signature during editing, the melody of the next note is sequentially played by pressing the musical tone adjusting switch 24 at the time of reproduction, thereby making it possible to freely change the song It is designed to be convenient for direct singing accompaniment or free play.

If you do not select the playback output of the preset song in the performance mode, you will only be able to play the notes while pressing each note.

In the case of a keyboard musical instrument, it is necessary to play a melody with the right hand and a chord with the left hand. However, since the present invention can independently constitute each part, only the melody can be played and the corresponding chord can be selected Since the chord composition according to the code can be varied, jazz accompaniment becomes easy.

In general electronic musical instruments, chords are directly played together with the left hand, or only predetermined chords are reproduced. However, the present invention has the advantage that the player can change only the chord melody arbitrarily, and also can check whether the composed chord is in harmony with the melody. In addition, the low-note musical scale, which is exemplarily shown at the bottom of the key code display section 11, is an audio section that can set or change a chord corresponding to the main melody. In addition, As a switch, you can also get the effect of a concerto playing with a different instrument from the main melody part, which is exemplified by the upper high-note pitch. Since the length of each score can be continuously added after deleting the key input contents by pressing the edit continuation switch (22), the existing score is sufficient. A tempo control switch 25 for determining the tempo of the entire song has also been added to induce correct reproduction of the song.
