Aswell as my goal to learn to read well enough to play any genre of music, I am also interested in using the keyboard in a band context. I am therefore, delighted to have discovered David Sprunger's website and the wonderful array of video lessons he provides based around his rhythmic patterns. I was initially drawn to his blues piano lesson section working through all the free videos before realising that it might be a good idea to purchase his very reasonably priced ($19.95US) original Pattern Piano and Keyboard lesson pack which I have done and am starting to work through.
Once I have completed it, I am looking forward to purchasing the complete Blues piano lesson series.
Well worth a look if you are not interested in learning to read and only interested in chordal accompaniment.
