These videos will discuss the concept of "embouchure" and the basic production of sound on each instrument. Embouchure is how a musician forms their facial muscles and how these muscles interact with the instrument. I recommend playing along with these videos and watching them multiple times to make sure you understand the concepts.
All Embouchure videos are taught at least in part by the "Embou-Sure" method Copyright W.I.B.C. Publishing Company, 1987.
