"You touch the sound you hear in your head." This is like touching a gentle animal: you touch it anticipating a response. What is the response in music? The next sound perhaps.
Touch is at once active and receptive.
Welcome to this day to day sharing of insights into music. My thoughts and my playing reflect my lifelong drive to integrate primary reactions to sounds with a sense of playfulness open to lyricism as to intellectual game-playing - the level of musical response endangered if not already extinct due to the endemic compilations of sameness that make up our soundworld.
