This book was developed rather than written. It contains material I use in daily warming up, material I use with students, and finger exercises I use when called upon to play baritone on short notice. THE WARM UP A warm up should be a preparation for playing. It should contain exercises covering the fundamentals of playing and should be brief. It is impossible for a professional player faced with a ten o’clock rehearsal to commute to the hall and practice for an hour or so.
