Here is an amazing piano solo of “Sweet Georgia Brown” played by Gyuri Villas. This piano style is very much like Oscar Peterson, and includes some nice Art Tatum elements.
This is a high level example of piano mastery by a very good player. Learning to play Jazz can be challenging. At my piano studio, here in Portland, students taking piano lessons or keyboard lessons who are interested in learning improvisation can get a good start by learning Blues Improvisation. Blues is a much simpler and easier style to learn than Jazz and includes many of the same basic concepts of jazz. I’ve taught Blues Piano to many students who are just starting out. It’s great fun, very exciting, and fairly easy to learn.
