This is a must for any flutist who trully cares for his craft! This book is trully a work of art! It explains everything from the reality of a sustained note to finger phrasing. It isn't one of those old texts that has absolutely no revalence to music. If you wish to play music it is one of the books you must read. With plenty of new ideas to try as you turn each page. It is trully mind-opening!!!
