I'm new to teaching lessons since I'm only a senior in high school, but I just recently started teaching my first student. He's in fifth grade and from what I know was doing really well at the beginning of the school year, but slacked off a lot throughout the year and is now really behind.
Anyway, he has a problem with not being able to get off the lower partial, and no matter what I tell him to do (more air, tighter embouchure, better posture) he will briefly hit the right notes and then slip back down the the lower partial. He's really motivated and wants to learn, but gets discouraged when he can't hit the higher notes. So it's not like he isn't trying.
Any advice on how to get him to hit the higher notes (I'm talking F, G, A in the staff-- fifth grade) more consistently?
