How to make a song on a hand-rolled piano is as follows:

First of all, composing a tune is the first step in making a song. Use the keyboard on a hand-rolled piano to compose your own tunes, based on your personal creative inspiration and musical theory. Secondly, making notes and chords is a critical step in making a song. The hand-rolled piano uses two membrane circuits to produce notes. The circuit is connected by pressing the keys with your fingers, thereby emitting the corresponding notes. At the same time, when multiple keys are pressed, you can create chords, which are combinations of sounds that sound multiple notes simultaneously. Next, making the beat is an important part of giving the song a beat and tempo. By controlling the time interval and intensity of the keys, you can create different rhythm effects to make the song more vivid and powerful. Finally, debugging is done to ensure that the hand-rolled piano can accurately play the produced songs. During the debugging process, you need to check whether each key can sound normally, and adjust the pitch and volume of notes and chords to achieve the ideal performance effect.
