- Bbm3DbM3Fm3Ab
Bb Minor 7, written Bbm7, is built from Bb, Db, F and Ab: the root, minor 3rd, 5th and minor 7th.
Its 3rd and 7th, Db and Ab, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass.
In the progressions here, Bbm7 is the ii7 of the Major ii-V Progression in Ab, the iv7 of the Backdoor ii-V-I Progression in F, the vi7 of the Deceptive Cadence in Db, the iii7 of the Major iii-VI-ii-V Progression in Gb, the i7 of the Minor i-vi-ii-V Progression in Bb and the v7 of the Whole-Step ii-V Chain in Eb.
