Milestones in Si

Milestones in Si

Miles Davis' modal pre-Kind of Blue composition anchors its two-section architecture on Dorian language and Lydian contrast built from B. Harmonic Minor adds brief tension against the otherwise open modal landscape. Working the Gm7 – AMaj7 changes prepares improvisers for the extended modal thinking that defines Miles' most influential period.

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 G to A (ascending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from A to G by whole 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. Over dominant seventh chords, B Mixolydian adds the flat seventh for an authentic blues-rock edge.
