39.94The important theory upgrade
Earlier you learned:
dominant 7th = V7.
That remains true in functional harmony.
Now your model must expand:
dominant-seventh quality does not automatically imply dominant function.
F7 can be tonic.
B♭7 can be IV.
C7 can be V.
All three have dominant-seventh quality.
Only one is functioning as the conventional dominant of F.
