Maybe he could attach a portable grill to the bell and kill two birds with one stone.

Well, knowing the true acoustical combination of wind and lips has helped me be aware of not having to muscle the lips. But nevertheless, I can't wrap my head around one blowing air into the mouthpiece then into the horn without the lips vi vibrating. And that vibration is what I've always known as a buzz.

Maybe you let the lips vibrate instead of using a forced buzz but you still have to relax and contract them as you ascend and descend, n'est-ce pas? And isn't that vibration a buzz?

Also, love the "offset" valve look. Very trendy

I had a friend in college who played an Olds Recording. It was one of the most unique instruments I had ever seen and was perfect for the type of playing he did. I hope you enjoy it.

I think it's useless. There is no direct comparison between "buzzing" your lips and creating a standing wave in a brass instrument. I can see how mouthpiece "buzzing" may be helpful, but lip "buzzing" seems worthless to me. We don't "buzz" at all in the trumpet -- we create a standing wave in the instrument with the passing of air through our embouchure. I think of the organ. In the organ, you have pipes which are sounded by a reed. You don't separate the reed from the pipe -- they are part of the same system. No reed, no sound, but no pipe, and you get a sound alright, but not anything like the sound you wanted.

I am against lip buzzing.

I was not aware, George, thanks.

On second thought, I was aware. I've got one strength for newest valves, another for 1st and 3rd valve slides, and another for the tuning slide. Whew. In other words . . "Yes".

I've mostly switched to B.E.R.P. too. What I like about Hetmann is its various grades.

I got a play test om a horn I ordered too. Nice touch. Hope it Arrives O.K. Enjoy.
