hey bill, when should i write a chord as a "slash" chord, like Fm/Ab? what i'm doing now is i try and see what the bass is doing, and if it's playing anything other than the root note i write it beside the chord. is that all there is to it?
pretty much if you can't think of any other good way to say it, but you can think of a way to say it as a chord over a bass note, then do it that way
