Small nitpick: > For example, the I - IV - VIIm - V7 progression below uses the same motions in A as it would in C, where the chords would be C F Am G7. Shouldn't that be "I - IV - VIm - V7" instead? (The transposition from A to C looks right, it's just the roman numeral for the 3rd chord in the text that is wrong).
