I have a besson class A that that looks like from the 1920's, and it sounds like it is in A instead of Bb so i was wondering if that is how it was made or if it is broken somehow, it seems to play fine but in A.

Any info would help.
Pictures to come

Two things come to mind:


1. It might be in a lower pitch than be use today.
2. It might be leaking.

If I were you I would take out a good tuner and figure out were exactly were it sits on the spectrum. A might be 425hz or 435... I would also check for leaks and make sure the valves aren't too worn down.

All of the above, but.........they were available in A too.

Hawkes listed Euphoniums in A, B flat & C in their catalogues.
