How to Play C7 on Piano

A major triad plus a flattened seventh. The tritone between its third and seventh is what makes it lean so hard toward the chord a fourth above.

Right Hand

Place your thumb (finger 1) on C. Use finger 2 on E, finger 3 on G, and finger 5 on Bb.

Where it sits

One note of this chord (Bb) is on black keys, so play it a little further back on the keys than an all-white shape.

Press all 4 keys at the same time. Keep your wrist relaxed and your fingers curved. The blue dots on the piano below show exactly which keys to press — they turn green when you play the right note.
