Features

To make a sound, a tap of the finger does the "bachi" position using the Right hand.
The pitch of the strings at the top and bottom is D.
The pitch of the string in the center is A.

The "sao" position is made to change the interval and a tap is made by the left hand.
The forefinger, the middle finger, and the ring finger are used usually.

The sound of ten in 12 music scales are used in the shamisen.
The position of ten is one octave.

Because the sound between 3 and 4 is not usually used, it is displayed as #.
Please note that it is a merely a symbol.

Because the sound between 9 and 10 is not usually used, it omits it.

【Cautions!】
Make sure the mute button is not on and volume is not set to minimum.

In order to play, you must tap the body of the shamisen and tap or hold the note you want simultaneously. This is to simulate strumming the instrument. Pressing only on the strings will not produce a sound.

We recommend locking your screen in the horizontal orientation for easier playing.
