I'm not sure if I'm allowed to post cadenzas on this forum since a cadenza is an extension of an existing concerto and not a stand-alone work, but I'll put it on here anyway just to see what happens! :D
This is my first attempt at a cadenza I wrote by myself for Mozart's Concerto, which is what I was learning on the violin with my music teacher at the time of writing.
EDIT: I posted this under Chamber Music, because I can't find a section for solo instruments beside piano on here.
A piano piece I wrote that looks back into my childhood and the good times I had in it. Sorry that the audio file can get really soft at times. I put in the right dynamics, crescendos, and decrescendos, and the software decides to be a rebel when recording the playback. Haha, but enjoy anyway!
I'll try explaining it. I have perfect pitch too, which means you can tell what a note is just by listening to its pitch. Say your music teacher plays D-flat on the piano without you looking at the keys and asks what note it is. If you can say D-flat right away without any bit of help, then you have perfect pitch.
I have an unfair advantage by having perfect pitch, so whenever I'm humming something random and it hits me like, "that would be an amazing motif", I go ahead and write it down, note for note.
Ken's method is, from what I've seen, pretty common, and it works! It's reliable, and serial muscle memory keeps those motifs in your hands for a little bit.
As for how it sounds... unless it's incidental music that will only be virtually realized, I've been taught to always write with the players in mind, as a super high priority. Unless it's an aleatoric piece, I tend to write using technological notation right away. It just keeps it in one area, which is nice.
