C# Major Chord Progressions for Piano

C# Major functions as the tonic — the harmonic "home" — in the key of C# Major. Every progression below resolves back to C# because it is the point of rest your ear expects after the tension of the dominant (Ab) or subdominant (F#). This page covers I – IV – V – I, I – V – vi – IV, vi – IV – I – V, and more, with every chord linked to its own page.

C# Major in Context

C# Major also plays a role beyond its own key: it is the dominant (V) chord in the key of F# Major, and the subdominant (IV) chord in the key of Ab Major. Its relative minor is Bb Minor, which shares the same key signature and often substitutes for C# in progressions like vi–IV–I–V.

The C# Major scale is C#, D#, F, F#, G#, A#, C.
