C at the bottom, then E♭ and G and B♭. Right hand 1-2-3-5, left hand 5-3-2-1. The black keys are E♭ and B♭.

How to play Cm7 on piano, step by step

  1. Start on middle C. That is the lowest note of the chord.
  2. Thumb (1): C
  3. Index finger (2): E♭
  4. Middle finger (3): G
  5. Little finger (5): B♭
  6. Press them together with the right hand. The left hand plays the same notes with fingers 5, 3, 2, 1 an octave lower, or just C on its own as a bass note.

The black keys are under fingers 2 and 5, with white keys under 1 and 3. The hand ends up at a middle depth, which takes a moment to settle into.

First inversionE♭ G B♭ C

Lighter than root position and less final. A flat third in the bass tips the chord forward, which is why it usually sits between two other chords rather than at the end of a line.
Second inversionG B♭ C E♭

Open and slightly unresolved. A fifth in the bass makes the chord sound like a step on the way somewhere, which is mostly how it is used.
Third inversionB♭ C E♭ G

The most restless of the four. The seventh is the note that wants to move, and putting it underneath the whole chord makes that pull impossible to miss.

If it sounds wrong

The chord sounds bright
The second note is E flat, the black key to the left of E. E natural would give C7.
The little finger is weak on the black key
It has to reach further into the keyboard than the thumb. Let the hand angle rather than stretching the finger back.
The chord sounds muddy
Four notes with two black keys can blur in the lower octaves. Play above middle C or use an inversion.
