I'm surprised there are so few responses - there must a good few more people on here that can play instruments..... or at least were pushed into trying at school / taught themselves later in life.
I am a trombonist and play mostly in orchestras for amateur musical productions. Plus occasional jazz band gigs and weddings, charity gigs etc
I can also play piano, but this is more of a hobby for playing at home - I only play in public once a year and it terrifies me (Christmas morning church service!)
