eioday we'll discuss buzzing; when, why and how. Happy practicing!
A few years ago there was a huge (by classical music standards) argument online about the pros and cons of buzzing on the mouthpiece. There were people protesting outside of local music stores, riots were started, others named their newborn children in support of their favorite mouthpiece manufacturers. Just kidding, but people really did argue.
People said buzzing was different from playing the instrument (it is, but not because you create sound in a different way), or that the way you create a buzz differs from playing on the instrument (also true). Neither of which mean that buzzing is a bad thing; far from it! Buzzing is a useful tool to have in your box of practice methods.
