C Minor Chord

The C minor chord contains C, E flat and G. On piano, keep C and G from a C major chord and lower E by one key to E flat. That one change gives you Cm, a minor chord with C as its root.

  • Notes: C-E flat-G
  • Symbol: Cm
  • E flat is the third

keep practicing

Play Cm, then C. Keep C and G in place so your ear can follow E flat moving to E.

Where is E flat on the keyboard?

Find C just to the left of a group of two black keys. The black key nearest E, at the right of that pair, is E flat. Add G, the white key after F. You now have the three notes C-E flat-G.

E flat can also be called D sharp on a piano because both names use the same key. In this chord, E flat is the useful spelling: the notes C, E and G are a stack of thirds, and the middle one has been lowered. That makes the difference from C major easy to see.

The letters Cm mean C minor. The "m" changes the chord quality, not its root. Minor Chord explains the same pattern from other roots.

What happens when the chord is inverted?

Root positionC-E flat-GC
First inversionE flat-G-CE flat
Second inversionG-C-E flatG

Use the inversion buttons above to compare the three positions. None adds a new chord tone. When the lowest sounding note of the whole arrangement is E flat, a musician can write Cm/E flat; with G in the bass, Cm/G. If a bassist plays C underneath, changing only your right-hand order does not change the overall bass note.

Inversions can make a change between two chords easier to play. For example, Cm in second inversion gives G-C-E flat. Move E flat down to D while keeping G and C, and you get G-C-D, a Gsus4 chord. Then move C down to B for G-B-D, a G major chord. Try each step slowly and notice that G stays put.

Is C minor always in the key of C minor?

No. Cm can be the home chord in C minor, but its notes also occur naturally in several major keys. In B flat major it is built on the second scale degree; in A flat major it is the third; in E flat major it is the sixth.

Play Cm-F-B flat-Cm, using the chords in B flat major. Cm begins the sequence, yet B flat is the major key's home chord. If you stop on Cm instead, the ending can suggest a different center. The surrounding chords and melody tell you more than the isolated chord name.

How does it compare with C major?

C major is C-E-G. C minor is C-E flat-G. The root and fifth remain in place. If you alternate the chords, you can focus on the moving middle note instead of guessing a mood from the whole sound.

A minor chord can support a quiet melody or a fast, energetic section. Tempo, articulation, instrumentation and the neighboring chords also shape what you hear. Compare the paired C Major Chord guide for the same three positions with E natural.
