I Have been playing for 4 years and my middle school band director wants some one to switch

It`s not very hard to switch to the baritone if you pick treble clef I switched over from trumpet to baritone(although i still play the trumpet)and at first i hated it because i couldent realy read bass clef but after a while it gets really easy, and keep on playing the trumpet because it really helps you hit the high notes on the baritone

My band director wants me to switch to tuba too, but I don`t want to because a hate base clef and it takes so much air for a tuba.

meh, tuba requires a bit more eair sure, but it requires way less pressure...
