Bbm13 Guitar Chord Chart and Fingering
Need B minor thirteenth rather than Bbm13? Jump to Bm13.
Count from Bb and the Bbm13 chord (Bb minor thirteenth) gives Bb, Db, F, Ab, C, Eb and G: a minor third, a fifth, a minor seventh, a ninth, an eleventh and a thirteenth.
The G is the thirteenth, and it is a natural note, which is what gives the chord a Dorian flavour instead of a natural minor one, where the sixth would be Gb. If the stack feels abstract, another look at ninth chords helps, since the thirteenth only continues the pattern. The Bb Dorian scale contains all seven notes.
Bb minor 13th guitar chord is also written as Bbm13, Bbmin13 or Bb-13.
