Chord Diagrams — Equinox in Sol# (Guitar)

Equinox in Sol#

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.

G# major (or Ab) lives at fret 4 on the low E string. All chords require barre technique, making it less common in guitar-centric songwriting but standard in piano-driven pop. Guitarists often use a capo to access friendlier shapes. G# is a intermediate-advanced-level key on guitar because the open G string is a half step below the root, creating dissonance — avoid letting it ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

The bass line moves through A# to D# (ascending perfect fourth), D# to F# (ascending minor third), F# to F (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 F to A# by perfect fourth.

Scales for Improvisation

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