I'm not sure if this is the right category for this post, but here goes. I was having a discussion the other day with my euphonium teacher. His main instrument is trombone, but he is always encouraging me to make the best euphonium sound I can make. In other words, he is not asking me to make a trombone sound on a euphonium.

Aside from the obvious difference that one uses a slide and the other uses valves, here's my thought about the difference between the two instruments. The trombone comes straight at you and demands that you listen to its commanding tone. The euphonium surrounds you with sound and seduces you with its sweet tone.

Tommy Dorsey might not agree with that comparison, but what do you think?
