Trombone: There is a serious shortage of trombone players at every level. From elementary school on up to semi-professional, trombone players are highly valued and sought after. Trombone players play in marching band, concert bands, orchestras, and jazz bands.
If you choose to play trombone, supplies needed: slide oil, slide grease (oil and grease are two different things!)
