Fading Taps

So my hands could easily be considered the shakiest hands. I have tries playing any musical instrument, but i just can't keep stable, and have always been sad. That's why, i thought about this app. Fading Taps is an app that utilises your tapping location on the screen to create sounds. Moreover, the location and speed of the tap would change the frequency and fourier transform of the Tap Sound Wave. That is, faster taps will make the sound wave have a higher frequency, while wider taps would create a wider frequency response, more oscillations means lower base frequency, and the ultimate goal would be to create sounds that are modulated by human movement. It would also have an effects library with different effects. My concept was that you could modulate the sound by moving your four fingers. I hope that this would have made music more accessible to those who have movement disabilities, because i sincerely think that playing music should be for everyone.
