One day many years ago a piano teacher showed me something which he said was trick used by Keith Jarrett. Basically the left hand would play any key – let’s say Bb – then the right hand would alternate using that left hand Bb for the 1 or the major 3rd or the 5th hence the right hand would play Bb major or D major or F major. A beautiful nice move.
So cool to listen to him speak accepting this award. I’ve listened to him with deep admiration since I was a teenager but never heard his speaking voice before. What a surprise (and no surprise) that he is reasoned and understandable. Why wouldn’t a genius musician be like that?
