C# / Db Chords Directory — Piano Keys & Guitar Voicings

The three most essential chords built on C# are C# Major (C#–F–G#), C# Minor (C#–E–G#), and C# Dominant 7th (C#–F–G#–B).

Together with C# Major 7th (C#–F–G#–C), these four chords provide the harmonic core for playing thousands of songs across pop, rock, folk, blues, and jazz.

The C# Major chord contains the root (C#), major third (F), and perfect fifth (G#).

The C# Minor chord lowers the third by a half-step: root (C#), minor third (E), and perfect fifth (G#). That single semitone change transforms the emotional tone from bright and resolved to dark and melancholic.

C#7 (dominant seventh) pairs a major triad with a minor 7th (C#–F–G#–B), creating bluesy harmonic tension.

C#maj7 (major seventh) pairs a major triad with a major 7th (C#–F–G#–C) for a dreamy, lush jazz feel. C#m7 (minor seventh) pairs a minor triad with a minor 7th (C#–E–G#–B), giving a smooth, soulful sound.

In the key of C# major, C# acts as the tonic (I chord).

Common progressions include I–IV–V (C# – F# – G#), I–V–vi–IV (C# – G# – A#m – F#), and the jazz ii–V–I (D#m7 – G#7 – C#maj7).

On piano, C# chords are played by pressing the constituent notes simultaneously (C#, F, G# for major) with your right hand, or playing the root C# in the left hand with chords in the right.

On guitar, C# chords can be fretted using open positions (where applicable) or moveable barre chord shapes rooted on either the 6th string or 5th string.

Suspended chords replace the third with a major second (C#sus2: C#–D#–G#) or a perfect fourth (C#sus4: C#–F#–G#).

Because they lack a third, they are neither major nor minor, creating an open, unresolved harmonic suspension that begs to resolve back to C# major.
