Why it sounds like that

C minor 6th is built from the formula 1, ♭3, 5, 6. The major 6th, A, adds a bright, unresolved colour to the minor triad. Compare it to C minor, which stops at the 5th.

What goes wrong with C minor 6th?

  • Letting the index finger lift off the B string, causing a muted note.
  • Strumming the low E string, which is muted because its open note is outside the chord.

When to use it

C minor 6th works as a tonic in C minor progressions, such as Cm6–Fm6–G7. Its bittersweet colour suits jazz ballads and folk fingerpicking. Try it with C minor or C 5th.

Changing to and from C minor 6th

  • Move from C minor 6th to C minor by lifting the pinky off the high e string and letting it ring open.
  • Slide the shape up one fret to the 2nd fret to play C♯ minor 6th.

Which voicing to use

The 1st fret voicing keeps the bass on C and suits strummed passages. The Cmin6/E♭ inversion at the 1st fret puts E♭ in the bass for a darker, more ambiguous sound.

Common questions

How is C minor 6th written?

C minor 6th is written Cm6, min maj6, or Cmin6.

What is the difference between C minor 6th and C minor 7th?

C minor 6th has a major 6th (A), while C minor 7th has a minor 7th (B♭). The 6th gives a brighter, more melodic colour.

Why is the low E string muted in the 1st fret voicing?

The low E is muted because its open note is outside the chord. Letting it ring would add a non-chord tone and muddy the voicing.
