Music with approximation of traditional instruments which I wrote for my guinea pig who passed away a week ago today.

I have a habit of uploading thinking I can't quite achieve a timbre in Xpressive, then achieving the sound right after upload therefore deleting and reuploading the next day. I finally got my singing syllable synthesis with MIDI note tracking to work in Xpressive (although it still sounds quite robotic). All instruments are mathematical expressions.
