The I-Isus-IV-V progression I-Isus-IV-V

Level: IntermediateMode: major

I Cmaj

IV Fmaj

V G7

Piano sound loads on first tap. Resolved in the key of C — every chord links to its full analysis.

What each degree does

ICmaj

Feels like home — complete rest, where the piece departs from and returns to. The major tonic, where everything settles.

IsusCsus4

The suspended tonic — the 3rd is replaced by the 4th, leaving home undefined as major or minor. A suspended shimmer that begs to fall to the 3rd and settle on I.

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.

VG7

Tension pulling home — the chord that 'wants to resolve' to I; it closes or opens sections. The dominant, the engine of the key.
