I composed Falling Up, a piano instrumental, in Dec 2014. The method I use most often is to randomly select 3-6 notes, and then compose around them. But I prefer to have someone else pick the notes so I can write something for them.
Selecting D, F sharp, G, and A myself, Falling Up took five minutes for the core and about three hours to finish. I hope you enjoy it – it’s the first composition I’ve played and posted.
