Technique Tip: High End Octaves

The challenge on the high end of the harmonica is moving from a 4-hole embouchure for blow octaves to a 5-hole embouchure for the draw octaves. Here are key things to keep in mind:
1) Be larger than you think that you need to be for your draw octaves (smile and frown at the same time to make your mouth wide).
2) Be smaller than you think you need to be for the blow octaves.
3) Move in half-hole increments (changing the size of your mouth already moves you a half of a hole).
