Mi Tritone Substitution
ii – bII7 – I progression in Mi major
Mi Tritone Substitution — ii – bII7 – I
In the E tritone substitution (F#m – F – E), the dominant V7 is replaced by a chord a tritone away — sharing the same guide tones but approaching the I from a half-step above. Lydian Dominant fits the substitute chord perfectly, while Dorian covers the ii. Bebop Major outlines the resolution. With seventh voicings (F#m7 – F7 – EMaj7), the chromatic voice-leading creates the sophisticated sound central to bebop harmony.
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 F# to F (descending half step), F to E (descending half step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from E to F# by whole step.
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.
