My thing now is the basics, scales and arpeggios. At age 48, I decided I really should know my way around the neck better.
So...any scale - all the notes on one string.
2 notes to a string,
3 notes to a string and
4 notes to a string (shift on the half steps).
edit#2: and of course, a scale in different positions up the neck.
I'm back into Bach's Sonatas and Partitas for Solo Violin after diddling with the Charlie Parker Omnibook for a few months.
Every day I try to read at least a page or two. I'm not working on memorization, just getting around the neck. I need to practice with a metronome, that would improve things drastically.
edit: there's also a bunch of standards I work on, mostly just learning the heads and playing arps through the progression.
