Since ancient times, people have painted various pictures on the walls of the cave. People always draw pictures. And the world of painting has been realized.

At first, I was thinking of a chorus like Gregorian chant. I first made a human voice-like sound with synths and effectors. This is a technique I've tried before. And this time, I thought about putting a pitch in the synth joystick in advance and letting that sound sing a song. However, it was not a matter of making a score, and it was extremely difficult to control the timing of pitch and timbre operations on the spot. In the end, I made a lot of sample phrases and put them together as a song in GarageBand.
