That's almost as much work as learning it!

you created your own system for actively refusing to learn to play normally. lol

i mean good job too I guess but I think just practicing would have been less effort.

This is especially funny because I think there's only 7 positions on a typical trombone anyway, and unless you have godlike lips can only hit 3 or 4 octaves across those. i played trombone through high school and it's like the easiest instrument, haha.

That's harder when playing plinky plonk though.

I did the same for the piano tbh. I was better at rhythm games than parsing sheet music so I'd practice and memorise pieces on something like Synthesia.
