The scene using the Japanese koto.It is tuned by the sound used in the "sea of ​​spring(haru no umi)", so you can taste the atmosphere without discomfort.
In Gamelan's scene, percussion instruments and whistles are tuned by the Gamelan scale (5 scale), and unique music is produced.
You can set the frequency, falling speed, and number of falling balls, so you can play according to the setting.
At the end of the performance you can save all the parameters at that time. The position of the ball made randomly is recorded as it is. Since it is played with exactly the same parameters, almost the same music can be reproduced. However, because it is a problem of numerical precision, it will not be exactly the same performance, so do not be afraid.
