Toccata means "to touch." Typically it is a fast-moving, lightly fingered or otherwise virtuosic piece of music emphasizing the dexterity of the performer's fingers. HOWEVER, notice that in this piece (and in all pieces) I am not playing from the fingers but from the elbow and forearm. Watch my arm and you will see the proper muscles work. If your hands or wrists hurt, quit playing from those tiny muscles in the hand and use the larger muscles in the forearm which are actually the muscles which move your fingers. In this piece since it only requires simple forearm rotation, my supinator and pronator muscles do all the work and my fingers effortlessly go along for the ride. Although, that three manual stretch at the end is incredibly stupid but, I'll learn my lesson when I sprain something. Stretching is bad.
Sorry about the aspect ratio being askew. I upgraded some software and all my videos are coming out funny. I need to take the time to figure out the settings. For more information on arm, hand and wrist injuries, go here:
