Thanks to Michael Joyce for these lessons. Other by Michael here
The exercises found in 20 Warm Up Exercises evolved during the 1980's. I was having more and more problems with my new live-in, Arthur Itis. There was no conscious effort to write a routine. My goals were to use an interesting chord progression that could be easily learned and put into subconscious memory to facilitate the concentration on the right hand.
None of these exercises are cast in concrete. I encourage you to create your on favorite chord progressions and practice these exercises. Also, especially with Exercises 17 and 18, improvise your own melodies.
