Equinox in B

Coltrane's slow minor blues builds atmosphere through Dorian improvisation on the tonic minor chord, Harmonic Minor tension approaching dominant resolutions, and raw Minor Pentatonic expression for blues-inflected phrases. The glacial tempo demands patience and motivic development over flashy runs. A study in sustaining intensity through simplicity rather than complexity.

Equinox 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 C# to F# (ascending perfect fourth), F# to A (ascending minor third), A to G# (descending half step). 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 G# to C# by perfect fourth.

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.
