I started out to learn to play the piano by myself. I created an app to view the midi notes as I don't want want to spend years to read musical notation. Then I created a music transcribe app to decode a song in my baby toy piano. I could not find the name of the song so I could not get the midi notes. Now I offer these 2 apps free to anyone who want to learn to play music.
I have also created an app to play piano on volca series.
If I suffer, will playing music calm me? A music can excite me to learn to play. Music is used to calm a king to sleep in the bible. Playing music is used for meditation.
