This series of studies hopes that students will find material arranged in a concise and methodical form that will be helpful in the development of a smooth and effortless legato, as well as an unusual degree of lip flexibility. These studies are not intended for beginners or young players. This book's intention is not to write exercises for the development of the upper register, but rather to develop a higher degree of flexibility in a lip already sufficiently strong to produce, at least in a fair degree, most of the high notes found therein.
