Hello, MY name is david and i am 14 years old. I played in band, jazz, swing, and more. My problem is that i play in band in middle school and from 3rd to 6th year i played the trumepet. Then in 6th grade my teacher asked if i would try out as a trombone. i accepted. And now 3 years later of switching off trumpet and trombone i was wondering if i would be able to play high still because sometimes it just feels like i cant play high anymore.
If you have any help I would appreciate it.

You`ll probably get more answers from people in the trumpet forum.
