- D#m3F#M3A#m3C#
D# Minor 7, written D#m7, is built from D#, F#, A# and C#: the root, minor 3rd, 5th and minor 7th.
Its 3rd and 7th, F# and C#, 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, D#m7 is the vi7 of the Deceptive Cadence in F#, the iii7 of the Major iii-VI-ii-V Progression in B and the vii7 of the Bebop Rhythm Changes in E.
