When you improvise, do you think of the chord changes or the melody? Both. This is an interesting question which Im unable to answer adequately. If the melody is the skeleton of the particular object, then the chord changes are its wardrobe, its changes of clothes. I tend to pay rather more attention to the latter than to the former. All I want is just a trace of skeletonthree bones from which the rest may be reasoned out.
