Understanding the Bb Minor sixth chord
Names and symbols
Bbm6 is the chord symbol for Bb Minor sixth; it is also written Bb-6.
How it is built
On Bb it is Bb · Db · F · G, stacking 1P · 3m · 5P · 6M. A minor third with a major sixth above it, which is an unusual combination: the chord is minor but its added note is bright.
How it is used
It is the tonic of the Dorian mode and the iv of a minor key, where it is a staple of the minor cadence. It is also a favourite in film noir and in gypsy jazz, where its ambiguity suits the idiom.
Its notes are the same as the half-diminished seventh a third below, which makes it a convenient reinterpretation point.
