Inner Urge in Sol#

Inner Urge in Sol#

Joe Henderson's post-bop minor composition challenges soloists with Altered dominant tension and Lydian color against a searching G# minor center. The harmonic ambiguity rewards players willing to push beyond conventional minor vocabulary into genuinely exploratory territory. The D#Maj7#11 – DMaj7#11 – CMaj7#11 – A#Maj7#11 – C#m7 – F#7 – Bm7 – Gm7 – C7 – FMaj7 – G#m7 – C#7 – F#Maj7 – A#m7b5 – D#7b9 changes develop command of altered harmony and the kind of harmonic courage Henderson embodied.

Inner Urge in Sol#

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 D# to D (descending half step), D to C (descending whole step), C to A# (descending whole step), A# to C# (ascending minor third), C# to F# (ascending perfect fourth), F# to B (ascending perfect fourth), B to G (descending major third), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to G# (ascending minor third), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to A# (ascending major third), A# to D# (ascending perfect fourth). 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 D# to D# by unison.

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.
