- Trumpet players have wild ideas about adding weight to their instruments. What is truth and what is fiction? And why do so many of us lack the vocabulary to communicate what is really happening?
I started repairing, modifying and building trumpets after you encouraged me to do so while laid off from General Motors back in 2006 or 2007. Trumpet players often mistake what they hear and feel behind the bell with no understanding oh how things are effected in front of the bell. They also do not understand what causes what and often misplace the what is generating their idea's about cause and effect. Changes in feedback behind the bell do not equal an equal change in front of the bell. I can build a trumpet that feels and plays like a Bach behind the bell but sounds like a Martin Com. in front he of the bell and the opposite is also true. If one is not measuring things empirically as well as taking notes on what you feel behind the bell and what the trumpet sounds like mic'ed up your are only getting a small understanding of what is going on! On top of that everyone has to use the same vocabulary or it is like a dog chasing it's own tail!
Thanks for sharing!
I watch a ton of your videos, I bought my first Harrelson because of them. I learned a lot about the science behind sound, vibration, and mouthpiece pressure. I cannot WAIT to play my new Harrelson!
I have started to understand some of these concepts as a result of customizing a Yamaha trumpet with a VGR, trim kit and other sorted parts. The simple act of re-installing the lead pipe brace changed the efficiency of the instrument, this efficiency can be misinterpreted as a change in sound quality, the horn “felt” darker but it fact was not. I agree that an apples to apples comparison is important to understand the properties of what’s really going on. Nelson Gutierrez, NYC.
Thanks for this informative video!
you're welcome
Great explanation thank you. But I wonder if some players want or need more feedback and less projection, and so the famed HBC would not benefit those players?
Two easy ways to get more feedback. 1) choke the bell tail 2) thin the bell. Both of these methods work, but thinning the bell significantly reduces efficiency and projection. The real question should be, "why does any player need more feedback in terms of sound?" Hearing aids would be the ideal solution.
Very informative thanks Jason
Very helpful explanation, thanks!
Would love to know your thoughts on traditional European cornets that did not have any mouthpiece gap. The receiver taper goes into a curved flare out into the leadpipe, a bit like the throat of a mouthpiece.
This feature is not unique to European cornets. Many North and South American cornets were designed with a recessed receiver design. The lack of gap was likely created to "reduce air resistance" at the insistence of critics (trumpet players). However, most of these players found that having no impedance change was more difficult to predict and less stable when playing partial to partial so the design was nearly abandoned. Conn offered several trumpet models with this design and they all lost popularity.

you mentioned that it is easier to play high on piccolo trumpet due to shortened overall length. Would the same also be true for cornet vs. trumpet
The Bb cornet and Bb trumpet are the same lengths.
The Bb cornet is slightly easier to play most partials in comparison to a standard Bb trumpet because of the added bracing. In many cases, some notes are easier while others are more difficult due to the added number of crooks, which present thin tubing wall structure on the outside of the bends. The length of each instrument is the same so there is no benefit in terms of a shift in the location of nodes and anti-nodes.
