bring the harmonica to your mouth so that its holes
push just past your lips and the outside of your mouth and are right
in front of your teeth—don’t simply reach forward with your lips and
put them around the holes. In proper position, your lips should rest
on the cover plates and press up gently against the fingers of your
left hand. In general, the deeper you can hold the harmonica in your
mouth while still breathing comfortably, the better your tone will
be. Make sure to maintain proper hand positioning, and keep your cup
open about halfway.
