I always start with long tones, sometime with a drone, then scales,
arpeggios,Lately I've been using Levinson's school of agility, I like it a lot. Then an etude or two, Storch-Hrabe or something else, then Bach, then Orchestral excerpts, then I practice for whatever Concert I have coming up, Then just for fun, I play along with the
pieces I practiced the orchestral excerpts to.
Then, depending on the day, and how much time I have, I'll work on my jazz improv, learn some tunes, and solo over some changes.
