The ii-V-I-IV progression ii-V-I-IV
Level: IntermediateMode: major
Piano sound loads on first tap. Resolved in the key of C — every chord links to its full analysis.
What each degree does
iiDm
The predominant par excellence — a soft minor leaning toward the dominant. It's the first step of the classic ii–V–I.
VG7
Tension pulling home — the chord that 'wants to resolve' to I; it closes or opens sections. The dominant, the engine of the key.
ICmaj
Feels like home — complete rest, where the piece departs from and returns to. The major tonic, where everything settles.
IVFmaj
A step out from home into the light — the subdominant. It sets up the dominant or resolves with a plagal ('amen') colour, opening space without sharp tension.
