When I started teaching flute, I went into the Musical Mastery WW book and read every. Single. Part. Of the flute section. I’m a clarinetist who was anxious and desperately didn’t want to mess up my flutes. There’s SO much info in the teacher section, it’s a little overwhelming, but a lot of it is VERY good information. Please make sure your students have access to mirrors in your class and spend about 4536729472 minutes making sure their embouchures are correct before going to the full flute. Okay, that’s an exaggeration but, honestly spend much more time on head joint than you think. Even in the spring, we’re doing head joint work, but working on vibrato etc.
