Bingo. "Notes" *are* "music". What can you do with yours?
As a musical exercise I made a solo drum "album" when I was 17 on my mini-disc player (now broken...and now I will have to spend money on an obsolete media to hear all of my discs). I didn't have anyone to play with for a while, as my sax player Travis was gone on vacation.
It was raining one day so I went outside and recorded that - with a bird's stark chirping - and played some bells and shook some giant ferns and jumped on our giant stick pile (lived next to a forest on a mountain) and there was the opening track.
Next track was back at the kit - a piece in 3/4 that I wrote a "head" to - played that - played some variations - soloed - and ended with the head again (a jazz tune, essentially - minus everyone else) Track 2.
Track 3 was a rubato thing that I remember not having much "direction" afterwards...sort of cliche stuff with mallets on toms and washy cymbals...meh...
By this time it was lightning outside so I went out and recorded some rain and thunder sounds - as a sort of constant theme for my "album"
Next was with a bunch of klanky toys and piles of sticks being thrown all over the kit - very sporadic with some interesting/random results.
etc etc - you get the point. I think a total of 3 people have heard the disc - 4 if you include my dad being in the house at the time - but I got a lot out of that. One of the biggest things being "Okay - it's just me playing these 4 drums and 3 cymbals: What can I do with them to make them interesting to listen to? *Can* I make it interesting to listen to 10 tracks of *just drumming*? Is this 'music'?"
Give it a shot. See what you can come up with by yourself.
