In this sampler-physical model duo, I started with the jazz song "In a Sentimental Mood", by Duke Ellington & John Coltrane. I played with the different instruments, and finally settled on the Saxophony physical model as my instrument. I mostly tried to match the algorithms when the two were in sync (both used sinuosoid, or both used logistic, etc).
In the overall composition, I hoped to achieve increasing chaos by adding more, and shorter duration duets towards the end.
