Road Song in Si

Road Song in Si

Wes Montgomery's groove-driven standard moves Bebop Major and Mixolydian language through a warm, soulful B swing with characteristic Montgomery ease. Dorian color adds depth to the minor passages and gives the standard its blues-jazz emotional texture. The BMaj7 – E7 – A7 – G#7 – C#m7 – F#7 – D#m7 changes are a direct line to Wes's iconic octave-and-chord approach to melody and improvisation.

B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

The bass line moves through B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to G# (descending half step), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to D# (descending minor third). A half-step bass movement creates a strong leading-tone pull that demands resolution. The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from D# to B by major third.

Scales for Improvisation

B 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, B Mixolydian adds the flat seventh for an authentic blues-rock edge.
