Why it sounds like that

B♭ minor add 9 is built from the formula 1, ♭3, 5, 9. The major 2nd interval between B♭ and C is the 9th that gives the chord its characteristic openness. Compare it with B♭ minor, which lacks the 9th and sounds darker.

What goes wrong with B♭ minor add 9?

  • Letting the pinky collapse and mute the E string, which kills the perfect 5th.
  • Placing the index finger too far from the fret, causing the C string to buzz.

When to use it

Which voicing to use
