Doing some reading as part of yet another attempt at becoming slightly less musically inept with regard to theory. Couple of things I don’t get with relation to transposing instruments, firstly- why? Why would you want an instrument to play an A when a C is written? Is it some sort of trick for composers to get a fuller sound by instruments at different intervals? And secondly the article said a bass guitar is a transposing instruments, well that’s the first I have heard of that, so is it or isn’t it? Thanks in advance for helping me in my stupidness.
