I am a new trumpet player, I started yesterday. I'm working on learning it for jazz band at school. Yesterday I spent about 10 minutes or so just messing with it. Making a sound then adjusting my mouth to see how the sound changes. I've played other instruments before but those were violin and auxiliary percussion. Today I spent a class period mess around and trying to learn how to play a song I like. I really want to learn how to play higher notes, I've been able to get a few here and there but only if I play loudly and it's few and far between.
