I am one for experimenting and even though I am progressing forward in trumpet and love it. I would just for a love of music like to learn another instrument...
I am wondering which instruments could be harmful to my embrouchre...
Instrumnets I have potential access through (via friends and family):
Keyboard/Piano (currently learning for theory and what not)
Clarinet (my mom has one)
Flute (my girlfriend)
Trombone (my frined has an old one)
