Secondary Dominant (V of ii) I-VI7-ii-V
Piano sound loads on first tap. Resolved in the key of C — every chord links to its full analysis.
A jazz turnaround with its first splash of chromaticism. The VI chord is made a DOMINANT 7th (VI7) so it acts as the 'V of ii' — borrowing tension from outside the key to pull strongly into the supertonic (ii), which then completes the ii–V motion home.
What each degree does
Feels like home — complete rest, where the piece departs from and returns to. The major tonic, where everything settles.
The V OF ii — an applied dominant pushing toward ii (the 'rhythm changes' flavour). A major VI with a 7th tonicising the predominant.
The predominant par excellence — a soft minor leaning toward the dominant. It's the first step of the classic ii–V–I.
Tension pulling home — the chord that 'wants to resolve' to I; it closes or opens sections. The dominant, the engine of the key.
