The Flute Tutor (patent pending) is used for: 1) Correcting habitual poor positioning. 2 ) Insuring that new students use the same position each time they pick up the flute. This will eliminate much frustration and make happy students and teachers! 3 ) Developing embouchure changes in order to play in tune instead of rolling the flute. 4 ) Developing extreme flexibility without rolling the flute in and out. The Flute Tutor does not work with the curved head flute.
