Mi Backdoor Cadence
iv – ♭VII – I progression in Mi major
Mi Backdoor Cadence — iv – ♭VII – I
The E Backdoor Cadence (Am – D – E) resolves to the tonic through the "back door": a minor iv chord moving to a ♭VII7 instead of the usual dominant V–I. Lydian Dominant fits the ♭VII7 perfectly, while Dorian covers the minor iv and Minor Pentatonic keeps the phrasing soulful. This cadential substitution is a cornerstone of jazz, R&B, and gospel harmony. With seventh voicings (Am7 – D7 – EMaj7), the smoky resolution is fully pronounced.
Playing in Mi major
E major is arguably guitar's most powerful key. The open low E and high E strings ring sympathetically as the root, while the open B provides the fifth. This triple reinforcement gives E-based riffs and chords unmatched depth and volume. E is a beginner-level key on guitar because both the low E and high E strings ring as the root, and the open B is the fifth — three open strings reinforce the tonic chord. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through A to D (ascending perfect fourth), D to E (ascending whole step). The mix of stepwise and leap motion balances smoothness with harmonic drive. When the progression loops, the bass returns from E to A by perfect fourth.
Capo Transposition
To play in E using familiar open chords: capo 2 with open D shapes; capo 4 with open C shapes; capo 7 with open A shapes. Choose the capo position that gives you the voicings you prefer — lower capo positions produce a fuller sound, while higher positions create a brighter, mandolin-like timbre.
Scales for Soloing
E major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, E Mixolydian adds the flat seventh for an authentic blues-rock edge.
Strumming Pattern
Use Freddie Green-style comping: short, muted chord stabs on beats 2 and 4 at 120-160 BPM. Keep the chords tight and percussive, lifting your fretting hand slightly after each attack to control sustain.
