I just came across this company who does these great jazz Improv instructional videos. It's The Jazz Conception Company; They are quite affordable, and much better than what you get when you google 'how to get started on jazz improv'. I'm really just trying to tune up my jazz skills that are borderline basic, and though this is a great place to start. Has anyone else found a good instruction program that works for them? Let me know! I'd love to give it a try.
JazzImprovisation.com is a site by Jim Snidero. I am sure it's very valuable material.
There is also http://JazzHeaven.com - full disclosure, I am the creator of that site.
Instructional videos & interviews with Lee Konitz, Jerry Bergonzi, Kenny Werner, Eric Harland, Ingrid Jensen and many more.
