Relative-Minor Secondary Dominant (V of V) vi-II7-V-I
Piano sound loads on first tap. Resolved in the key of C — every chord links to its full analysis.
A turnaround that starts on the relative minor (vi), then raises the supertonic to a DOMINANT 7th (II7) so it acts as the 'V of V' — tonicising the dominant before it resolves home. The chromatic II7 injects a jolt of forward pull into an otherwise diatonic loop.
What each degree does
The relative minor — the tonic's reflective shadow. It often replaces I in a deceptive cadence, where you expected home and its sad side arrives instead.
The V OF V — an applied dominant pushing toward the key's dominant. A major II with a 7th, extra tension before V.
Tension pulling home — the chord that 'wants to resolve' to I; it closes or opens sections. The dominant, the engine of the key.
Feels like home — complete rest, where the piece departs from and returns to. The major tonic, where everything settles.
