This allows you to vibrate the reeds in the right height / intonation. The cold air instead is synonymous with velocity and so it might come out a sound forced. 2) Create a “sounding board” in the mouth a bit as do the singers ….. we will have a darker sound and rich harmonics ……. 3) Think of singing the melody you are playing in order to facilitate our musical sensibility.
