Inner Urge in Fa

Inner Urge in Fa

Joe Henderson's post-bop minor composition challenges soloists with Altered dominant tension and Lydian color against a searching F minor center. The harmonic ambiguity rewards players willing to push beyond conventional minor vocabulary into genuinely exploratory territory. The CMaj7#11 – BMaj7#11 – AMaj7#11 – GMaj7#11 – A#m7 – D#7 – G#m7 – Em7 – A7 – DMaj7 – Fm7 – A#7 – D#Maj7 – Gm7b5 – C7b9 changes develop command of altered harmony and the kind of harmonic courage Henderson embodied.

F major is the gateway to barre chords. While F itself requires a full barre at fret 1, the remaining diatonic chords (C, Dm, Am, G, Bb) mix open and barre shapes. The open high E acts as Fmaj7's seventh, adding unexpected richness. F is a intermediate-level key on guitar because the open high E string is the major seventh of F, creating a lush Fmaj7 resonance even in basic shapes, but the F barre chord itself is the first big hurdle for beginners. 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 B (descending half step), B to A (descending whole step), A to G (descending whole step), G to A# (ascending minor third), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to E (descending major third), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to F (ascending minor third), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to G (ascending major third), G to C (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 C to C by unison.

Scales for Improvisation

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