Trumpet/Cornet Airway Question


Valve Bypass
Valve Bypass  
Greetings - I just bought a Buescher cornet on eBay. Horn-U-Copia dates it very likely to 1911. It has an unusual airway path. The mouthpipe enters at the third valve, takes a bypass to the first valve, then goes to the second valve. The pipe to the bell exits from the second valve. Was there an advantage to this configuration back in those days? I will attach an image.  Thank you.

Buescher certainly thought there was an advantage. They did it for "improved air flow"... except there is very little air flow in the cornet, as it is mostly a resonant system. You could take the tubing and tie it in a knot and the cornet would still play well.

So, in reality, it doesn't do much to affect playability. If you look at the 1909 catalog on Horn-u-copia, you will see their reasoning behind this system. While it is true that a constriction in the tubing may affect how the instrument plays, it's because of the location of nodes and anti-nodes in the resonant air column, not any air flow restriction. Renold Schilke would put slightly larger or smaller tubing in certain locations in this instruments for that reason.

I can answer your questions about Buescher trumpets and cornets. I have been playing Buescher for 35 years and collecting for 7.


I first started playing my grandfather's Buescher 400 trumpet in 1975. Since then I have done a lot of research, including original catalogs and advertisements that I own, correspondence with other Buescher owners, and obtaining my own Buescher collection, including six trumpets and three cornets.

I am a technical writer with 15 years experience. I have also been playing trumpet since 1975 and collecting Buescher for the past 7 years.
