Baritone/Euponium (There is a difference!!!) for about 9(ish) years. This is my principle instrument (always and forever) i started in the 6th grade and absolutely loved it.
Trombone (self taught for HS jazz band). I had taught myself some in Middle school. Once I moved I decided I wanted to play in jazz band so I touched up my trombone skills and auditioned my senior year.
Clarinet, Flute, Piano, Guitar all self taught because I was bored.
