C major piano chord

How to play C on piano

First, find C, the root of this chord. Then add E, the major third. Add G to complete the triad.

Play the notes together to hear the harmony, or one at a time to hear how the intervals form the chord. Start at a comfortable octave; the diagram shows one reference voicing, not the only valid place to play it.

What makes C distinctive?

C major is often the first piano chord students encounter because its three notes, C–E–G, are all white keys and form an easy visual landmark.

How does C compare with a related chord?

Compare C major to A minor (A–C–E). C and E are shared, while G moves up to A; this gives an accessible first harmony exercise.

A practice exercise for C

Play C–E–G, then keep C and E steady while moving G up to A. Reposition A below C and E to hear A minor in root position; the original G-to-A move alone gives a different voicing. Name each chord tone before you play.

One mistake to avoid

C major chord is not the same search task as the chords found inside the C major scale. A chord is three specific notes; a key contains several harmonies.

Finger numbers depend on your hand size, octave and musical context; there isn't one universally correct fingering for every voicing.
