I seem to be spitting into my trumpet much more than I should be, and I think the problem is getting worse. Any ideas about why this is happening, and how to correct it?

you play any other instraments? happens to me sometimes when iv been playing the horn allot and pick up the trumpet and cant make a sound into it , takes time to adjust.

yea....after a few months of playing Horn, i went back to mellophone(we use 6v mouthpieces that are kinda trumpet-like) I noticed after a few minutes that i was spitting all over my Mellophone :-( its probably something that fix itself with a lot of pracice

im having embochure problems, my jaw is moving and my greeat teacher says it shoudlnt be, she reccomends i switch to something similar, wut do u reccomend she says baritone or french horn, wut should i do

If you don't want to switch, try buzzing.
Try getting pitches.

If you want to switch, I'd say either french horn or trombone. Horn is a beautiful instrument when played correctly, and trombone is powerful and versatile. Baritone is a background instrument that, though important, is basically seen and not heard in an orchestra or band. Let me make my apology in advance to all the baritone players I just ticked off.
