OK, no doubt this question has been asked before, but would be interesting to see which way people here do it.
For my part as a guy who has played cornet in a brass band and trumpet in a general entertainment, (Mainly sax's) band, I can read and play to the tadpoles on lines, and also with a bit of work on finding the right notes, play a tune without the dots. I also did a bit of messing about on guitar with only a basic knowledge of a few chords. So I suppose you could say I can do a bit of both.
However who else can read music and play from it, and who are the guys who get by without knowing what the written music means and play entirely by ear or what they hear.
