How to Play the C Chord on Piano: Step-by-Step

Playing a clean C major chord involves simple hand positioning and finger placement. Here’s a clear, beginner-friendly guide to mastering it:

Hand Position: Sit with your hands relaxed over the keyboard.

Right Hand (common starting position):
- Index finger (1) on E (the black key directly above middle C or one above middle C row)
- Middle finger (2) on G (the black key slightly further right)
- Thumb (1) or third finger (3) can also support for stability
Play as a block chord: Strike all three notes simultaneously for a full sound—avoid fingering too slowly at first.

If playing piano studio-style with hands separated, use thumb, index, and middle finger as explained above, ensuring minimal hand strain.
