In a strange mash-up between painting and music, developer LeafNotes has released Soundbrush. Soundbrush works by drawing lines or shapes. Those lines and shapes turn into corresponding sounds. Each paint color stands for a different instrument (for example, blue is a piano).
The artist-musicians using this app get to hear the notes as they’re drawn. Users can even go back and delete previously drawn notes by double tapping; so more refined and thought-out pieces are definitely possible with Soundbrush.
Soundbrush uses both major and minor and major and minor pentatonic scales as well as the blues scale. A musical grid can be displayed to help pay more attention to exactly which notes are being drawn on the canvas.
Users with no experience with either drawing or music can take a stab at the app and still have plenty of fun. While there are no templates for new users to play with, there is the video below posted by LeafNotes showing the creation of a song/painting and how it sounds.
