Equinox in La

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 major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through B to E (ascending perfect fourth), E to G (ascending minor third), G 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 B 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.
