Why it sounds like that

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

What goes wrong with B♭ minor 6th?

  • Letting the pinky collapse onto the G string and deaden its open note.
  • Strumming the low E string, which is muted because its open note is outside the chord.

When to use it

B♭ minor 6th works as a tonic in B♭ minor progressions, such as B♭m6–E♭m6–F7. Its bittersweet colour suits jazz ballads and folk fingerpicking. Try it with B♭ minor or B♭ 5th.

Changing to and from B♭ minor 6th

  • Move from B♭ minor 6th to B♭ minor by lifting the pinky off the D string and letting it ring open.
  • Slide the shape down two frets to the 4th fret to play A♭ minor 6th.

Which voicing to use

The open voicing keeps the bass on B♭ and suits strummed passages. The 6th fret barre voicing keeps the same bass note but adds fullness for higher-register lines.
