Rotating the prime is simply revoicing the notes. If you would like for the prime to spell a dom7 you'd have to invert it. Let's look at it as notes:Quote:

Here's a little problem for the the idea of Forte primes as significant. The prime for the dominant 7 is [0,2,5,8]. No rotation of that makes a 7th.

Prime (0258): C .. D .. F .. Ab

Inverted form: E .. G .. Bb .. C, there's your dom7.
