Before even contemplating playing over changes remember that you have to feel the shape and contour of each chord in those changes. I will in between the fun and games start making small clips on what to play on lets say a Min7 chord,a static chord. Then a Maj7 chord etc. Well before these chords mesh together we will study the shape and tools to deal with each singular chord and juice whatever we can with whatever tools we have. Umpteen books and tutorials will give you a thousand ways. However the sound is the same and we have to learn the ways to express ourselves in the confines of ONE chord.Videos to come...Do refer to the scale chart that has been shared on this page and I will use common tools to make some music happen.
