I'm teaching a couple of people to play trombone, and both of them turned up with tutor books in bass clef. If I want to steer them towards brass bands, they will have to learn transposing treble as well. Is it time that new music and set test pieces had the option of tenor trombone parts in bass or tenor clef? I can see some difficulties: Lots of music already published in treble clef Leger lines for 1st trom in b.c. How to print the full score I think that the option of concert pitch would make it easier for young / beginner players to try brass bands while they are still playing in other ensembles. What do you think?
