So What in B

So What in B

So What in B — Miles Davis's modal manifesto from Kind of Blue. The entire head lives in Dorian mode; the bridge shifts up a half step to Eb Dorian. One scale, infinite expression. Changes: Bm7 – Cm7.

So What in B

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 C (ascending 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 C to B by half step.

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. Layer in the full major scale for melodic runs, reserving the pentatonic for riff-based phrases.
