Triad Diagrams — A# Backdoor Cadence (Guitar)

A# Backdoor Cadenceiv – ♭VII – I

The A# Backdoor Cadence (D#m – G# – A#) resolves to the tonic through the "back door" — a minor iv chord followed by a ♭VII7, bypassing the usual dominant V–I. This unexpected approach produces a smoky, soulful resolution central to jazz and R&B harmony. With seventh chord voicings (D#m7 – G#7 – A#Maj7), the backdoor quality is even more pronounced.
