I have assumed that if I want to indicate a D♯ major chord with a dominant 7th, I would spell it D♯7 (because that is the order I would say it - D sharp 7).

But that would imply that this chord, Gâ™­6, is a Gâ™­ chord with a 6th added on. But then I wasn't sure how to distinguish between that and a G major chord with a flatted 6th. Because without knowing the convention I might think that the latter would also be spelled Gâ™­6. But that can't be. Is there a lesson for chord spelling, or can someone just tell me. (And to go further, how would you spell Gâ™­ with a â™­6th)?

Thanks,

Dave
