My Funny Valentine in F
The F reading of My Funny Valentine: built on a descending chromatic bass over a static minor tonic, one of jazz's most haunting devices. Aeolian and Dorian blend naturally; Harmonic Minor is essential over the V7. Changes: Fm – C7/b – Fm7/Bb – Dm7b5 – C#Maj7 – A#m9 – Gm7b5 – C7b9 – G7b5b9 – Cm7 – F7b5b9 – A#m7b5 – D#7b9 – G#Maj7 – A#m7 – G# – C7#5 – C7 – Fm7 – D#m7 – D7b9 – E9 – D#m9 – D7b5#9 – D#7.
Key of F
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 F to C (descending perfect fourth), C to F (ascending perfect fourth), F to D (descending minor third), D to C# (descending half step), C# to A# (descending minor third), A# to G (descending minor third), G to C (ascending perfect fourth), C to G (descending perfect fourth), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to A# (ascending whole step), A# to G# (descending whole step), G# to C (ascending major third), C to C (ascending unison), C to F (ascending perfect fourth), F to D# (descending whole step), D# to D (descending half step), D to E (ascending whole step), E to D# (descending half step), D# to D (descending half step), D to D# (ascending 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 D# to F by whole step.
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.
