So yeah, I just transcribed the sheet music of Nyan Cat for alto saxophone. XD
Well, not really. I just found the sheet music on the internet, and transposed it to a easier, more playable key. Moving everything up a semitone turns the key signature from five sharps to none. Still took a while to put everything in MuseScore (free music writing program) though.
From now on, I shall play this in band class to annoy everyone.
The difficulty level of this piece is just about right, and it would make a great technical etude for senior concert band.
So, uh... Try to play this on whatever instrument you play? XD
