OK, maybe a few ... Does the concept of the relative minor apply to keys? Does that technically make the key of D-minor the same as the key of F in terms of accidentals? If not, what am I missing here? Thanks.
Yes. Yes.Technically and absolutely. You're missing alot. "Harmony and Voice Leading" by Edward Aldwell and Carl Schacter" 2nd Edition Harcourt Brace& Co. Orlando Florida 32887 This will answer all your questions and then some.
If you mean key signatures (rather than accidentals) then yes, you're right. F Major and D Minor both have the same key signature. Ditto for C Major & A Minor, G Major & E Minor etc.
Key signature! One of those basic terms that was on the tip of my mind when wrote that original post. Yeah. I guess was thinking about the sharps and flats -- accidentals, right? -- in the key signature ... Thanks!
