I play the euphonium in band and I`m pretty good(made all district, too lazy to try out for state) anyway my band director is hassling me to switch from playing tc to bc (I used to play trumpet) how hard would that be to do?

Hello anyone there?

the key to clef changing is just doing it. Some people can do it like nothing but others its an uphill battle. The key to it(at least for me) was to stop transposing the new clef, but to just learn to read an all new clef.

So... just do it.

Most Euphonium peices are written for bass cleff (most).

Its good to know know both, but Bass is your best bet. But yeah, just sit down and just do it. WOnt take but a week to get the basics, usually faster.

At this point I`m working on Tenor and Alto cleff. So prretty much, any key for any intrument will be a breeze for you.

Here`s a good way to learn bass clef when you already know treble. Play through your scales while reading them in bass clef. Eventually, it will become second nature. Scales, arpegios, and etudes all help, just read a lot. Eventually it will be easy. And yeah, all euph/baritone players should read bass clef. The only reason why treble clef parts exist is because lots of euph players are converted trumpet players.

Or, just do what I do. I read treble clef Bb parts (Euph TC, trumpet, tenor sax, etc.) by reading it in tenor clef and adding 2 flats. I guess that would be the wrong direction though....

For tenor cleff, just read the notes as if they were in treble cleff (as long as you have a Bb instrument) with the added key signature. It only works if you have a Bb instrument.
