Yeah I'm with you on most of what you just wrote. For me it definitely is more of a mental thing than a question or pure sound production, and definitely not about strength building (I'm not so convinced that the latter are universal among people who advocate buzzing though). Perhaps you're right that I should use a different term than "buzzing" in the explanation of my approach. But one thing is I find it needlessly confusing to use a different term when what I then use as a practice tool is mouthpiece buzzing. Also I like using it almost because I mean it differently: I don't want students to think of the "buzz" as just the lips vibrating, I want them to think of it as a complete system that includes the airflow itself, all the ways in which we can manipulate the airspeed, and all we can do to "tune" the resonance. Basically all of the things we do have to do when playing.harrisonreed wrote: Tue Mar 03, 2026 1:33 pmYes, I 100% agree, and in my mind this is describing Set->Slot->Adjust, which is what I'm now certain you do, just like probably nearly every great brass musician does (though they may not realize it). The act of setting the tongue shape, the corners, the mouthpiece placement, and the air is everything. The "buzz" isn't involved in this, and it sounds like you and I are in agreement -- the "buzz" is a result of this "set" interacting with the horn and the "buzz" comes out of that, and you can choose to fall into the slot or fight it. A synergy, not a cause and effect.LeTromboniste wrote: Tue Mar 03, 2026 12:26 pm Surely you agree that your air speed and lip tension (for lack of a better term) have to be a certain way for the right note to come out on the horn, no? Otherwise you'd only have one note per position. What I think is that it's not a binary between either far enough that the wrong note comes out, or close enough that the right note comes out. I believe it's a whole spectrum. You get far enough on that spectrum and the wrong note comes out. You get close enough and the right one comes out. But at one end of the spectrum, there is an optimal airspeed and overall embouchure for any given note at any given dynamic and for any given desired tone colour, that will give you the result you want with the least effort and the most reliability. (...)And getting that optimal setting requires us to really follow the musical line attentively and with great focus in our mind's ear and that our technique follows that.
But as you were describing what you do and what can go wrong you say:
Which is describing what happens when you do not slot correctly. What this is is that the hypothetical 'you' didn't set properly, and you are out of the slot. And the horn absolutely will hide that if you're close. The word "buzz" has no place in what you're describing except to highlight that if you think about "controlling the mechanics of the buzz" what you're really doing is leaving the slot. You either fall into the slot and the synergy or you "buzz" and fight it.Ultimately that's not a problem with the buzz itself, on a mechanical level of sound production, but a problem of imprecision in the connection between our mental "ear" and the mechanics of the buzz, that is partially (and sometimes quite well) hidden by the horn.
I think the reason I keep coming back to it is that language is important, and using language or terms that don't describe what is actually happening will cause confusion for students. Talking about buzzing to describe anything in the mechanics of playing brass, especially with it generally understood that you can "buzz" the mouthpiece, implies cause and effect. But I believe that it's not that the "buzz is imprecise" or the "slide is imprecise", it's that you're fighting the slot and the slide is in the wrong place. Those might actually mean the same thing. But the descriptive language is very different and could possibly lead students down very different paths in their approach to playing.
This brings it back around to what I was saying about buzzing being a potentially useful practice as a way to mentally focus prior to performing a task. And you're saying it can help your mind "hear" the pitches, like singing might. I can buy that. I can totally get that. I do not believe the vast majority of buzzing advocates think of buzzing that way. They seem to see it as a more pure form of sound production and strength building exercise that directly translates to what sound will come out of their trombone.It's not just (or even mostly) about the buzz itself, it's the tongue arch, the size and shape of the oral cavity, the airflow up from the lungs, how I tune the resonance inside my body to the resonance of the instrument. Mouthpiece buzzing helps me make sure I'm in this mindset of always closely following the musical line with my mind's ear and with my overall technique. If I'm buzzing a phrase on the mouthpiece and every note is as written except a couple that are wrong notes, that means I'm either audiating it wrong, or my technique is not following my mind. Either way, that means my focus is at some level not consistent, and things get sloppy.
Again it's not about what my lips actually do when I'm buzzing. It's not the same as when playing, but that's not the point of it. It's about building a mindset of being precise in every aspect. Including phrasing and shaping too.
And I also don't fully agree on the idea of just letting the horn dictate things and take care of slotting completely. I don't agree that playing off-center necessarily comes from "forcing" the buzz away from where the instrument wants it to lock. I think the "slot" is not a single point, it has a certain width, different on different notes, and different on different instruments, and that merely letting the horn dictate the slotting is not enough to always be in the optimal spot. The horn will slot, but it won't bring you to be exactly in the center either. There's room within the slot for you to manipulate things. And even if it did, wouldn't it still be more efficient to be in the center on your own instead of relying on something external to you? From experiencing it often enough in my own playing and in others', including people who never buzz, I'm convinced that there is another extreme in the approach you advocate for, that one can become overly reliant on the horn dictating the slotting, and that comes with the risk of becoming disengaged from the sound production and failing to implement all the small details involved in getting that consistent optimal setting.
If we ever meet, you'll have to try playing by D bass sackbut, and I think you'd see what I'm talking about. The slots are incredibly wide, and the instrument will not force you to play in any remotely well-defined center by just being "set" and blowing into it. If you just rely on the horn to dictate the slotting, you'll just have a big woofy sound with no core and no clarity, and articulations that roll on you. You have to do everything internally and find exactly the right setting for each note, and be constantly super aware and focused, otherwise you're toast. It's exponentially harder to control than any modern trombone, and it really shows you the limits of letting the horn slot for you.
