Chord Diagrams — Equinox in La# (Guitar)

Equinox in La#

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.

A# (Bb) major requires barre chords rooted at fret 1 on the A string or fret 6 on the E string. Despite the barre demands, it is a common key in funk, New Orleans R&B, and brass band music. The open D string can ring as the major third for added color. A# is a intermediate-level key on guitar because the open D string is the major 3rd of Bb, adding a bright color if allowed to ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

The bass line moves through C to F (ascending perfect fourth), F to G# (ascending minor third), G# 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

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