I specialise in Wind, although I only consider myself a performer on Clarinet.
I've been kinda brought up to try out lots of different instruments (my first clarinet teacher played clarinet, flute, saxaphone, oboe, bassoon, viola and piano to grade 8+)
Because I want to be a teacher, I want to be able to (technically) understand as many instruments as possible, just so I can help out people who need technical advice. However I don't pretend to be able to produce feeling or musicality on any instrument I learn, just the clarinet. :ninja:
It also helps when I'm composing, since I know how difficult certain parts will be.
