I've been told that I should be able to see that a movement like [G7 Cmaj7] and [C7 Fmaj7] are the same, and also hear them as the same, but I don't get it. Would you please explain it to me?
what they are probably trying to tell you is something you'd really only know by hearing it for yourself. has anyone ever showed you the trick where they play 'row row row your boat' starting on C, then they play the same song starting on Ab and it still sounds like the song even though it's different notes
