I understand and in the context of how you use the word buzz I agree, but a vibration of the lip double reed can also be called a buzz.
I think this is where the original issues sprang from.
If the lips move together and apart rapidly then the descriptive word for the sound that they create can be called a buzz.
What can we call it if not a buzz, a stuttering of air, a rasping, a flapping, a fluttering, a thrashing, a trembling, an oscillation, a quivering. When a student blows air into a mouthpiece and no sound comes out what do we do, give them a descriptive visual clue they can understand or simply say keep blowing, until they either get it or give up.
I have seen beginners blow and blow and blow and never get a sound, or they blow for 10 minutes and a raspy tone appears and then disappears and never reappears.
I would suggest that simply avoiding using the word buzz leaves us with "blow until your lips make a noise", and that is just plain unhelpful.
In Saxaphone circles buzzing of the mouthpiece is a well known and legitimate term and some players want to cultivate that sound and they use the word buzz to describe it, so why cant we use that term.
There are Sax pages named "That classic sax buzz"
And in describing Sax buzzing it is a legitimate way of playing and producing a Sax tone.
However we slice it a desirable musical tone in woodwind can be a buzz.
So in other instruments use of the word buzz is acceptable so why is any use of the word buzz unacceptable in Trumpet.
Maybe we should define the term buzz better rather than try to stop its use entirely.
I deeply suspect that because for many decades Trumpet teachers have been teaching students to buzz, the collective knowledge is that buzzing is good, and since some buzzing is known to be bad, I submit that we need to better define the term buzz and declare what is an acceptable buzz and what is not an acceptable buzz.
I am completely opposed to buzzing myself but I see buzzing as part of correct tone generation, and there are many advocates of buzzing possibly the majority of players and teachers see buzzing practice as essential.
In my case I see myself as buzzing as part of tone generation and I speak from experience here my tone has been complemented many times over the years as being very smooth so thinking of buzzing as part of tone generation does not have to mean we produce a bad tone.
If we cannot find a slightly better definition for teachers to use then they may just ignore the issue and continue to teach buzzing as they do now and students will continue to buzz badly and maybe students will make the same mistakes over and over again.
This perhaps is an opportunity to try to make a better future by describing to beginners better than at present how we generate tone and how buzzing fits in the picture.
I see two forms of buzz, the bad buzz that you correctly oppose as do I, and the buzzing that must happen when lips vibrate together.
When playing a low pedal for example what is sounded if not a buzz.
There must be a middle ground here.
I welcome your thoughts on this DR-GO.
