Johand, please see my posting from 12-26-2014 at http://www.irealb.com/forums/showthr...ercises/page27. You can find the Orta book at Amazon.com: https://www.amazon.com/Jazz-Etudes-P...s=orta+michael If you don't know what to do with your left hand, get a copy of The Jazz Piano Book by Mark Levine. I hope this advice helps.
