I must admit: I normally don’t warm up much because of limited available time on the horn. Normally i would do some lip slurs, a few scales, some blast in the lowest register, and then playing some popular tunes as an additional warm-up before proceeding to more serious stuffs.

However, since I bought a tenor horn and a bass trumpe (which both use smaller mouthpieces and I normally play them in higher register), I have noticed that if I warm up on those instruments first, both my tones and lower register on the bass trombone improve at least somewhat. I don’t know whether it is just my feelings or not, though.

Have anyone got an experience like this?

Could it be that your perception gets altered when playing a smaller, higher-pitched instrument?

I know that for myself, when I want to at least think I am sounding better on my larger horn, I will play it with a smaller, tighter mouthpiece for a while and then let out a sigh of relief when I revert back to the larger, more open size I use for that horn! :amazed:

What I don't ever do is to play my Eb tuba first! The big, mellow and sweet sound on that vintage Olds totally messes with my trombone sound perception!

sabutin, of TTF, when practicing several horns in a day, would work the smallest first, largest last.
