I’m a Junior in college. I have ten years of experience playing trombone but have been on a three-year hiatus. I only recently was able to borrow an instrument from my school as I am unable to afford one and our music program is not very large. I know I haven’t played in a while so I’m sure I don’t sound on par with what I once did, but I don’t think I’m that bad?? Have I really lost that much ability, while playing tuba consistently for the past five years, or is it my instrument/mouthpiece or both? Any advice on figuring this out would be awesome.
