the first time the euphonium was ever mentioned in press, it was in the 1880s
The trumpet reviewing it called it a foghorn and said it sounded bad enough to make a quaker kick his mother in law
in 2004 another trumpet said it was tonically better and that it is just as agile as a trumpet
and another fun fact, the two notes above my pedal Bb have the same fingering- 1234. I have to change the notes by lowering my top lip on the first of the two, then fixing them on the 2nd.
