The first grade students last year learned to audiate (hear in their minds, predict) I, V7, IV and V7/V in major; i, V7, iv in minor.
This year, they not only remembered those, but have added V7 of vi, V7 of ii, and V7 of V7 of V7 of V7.
Translation: they know the changes to "5 Foot 2 Eyes of Blue" which goes (in C) C, E7, A7, D7, G7 C.
This Little Light of Mine goes at the end: C, E7, a, D7, G7 C. Almost half the children recognize and identify the difference in the two changes: E7 to A7, or E7 to a.
For the V7 of ii, they know that in "Take Me Out to the Ball Game."
"Buy me some peanuts and Cracker Jack I don't care if I ever get back" goes (in C again) A7 d D7 G7.
Quadruple dominant, triple dominant, dominant of the submediant, dominant of the super tonic.
If anyone would like to add to the list of songs that have similar changes, I'd be really happy.
