Angel Eyes in F
Angel Eyes in F — a dark, brooding ballad with sustained minor tension. Dorian suits the extended minor vamp; Harmonic Minor tightens the cadential moments; blues inflections add emotional weight. Changes: Fm7 – C#7/c – Fm6 – C#9/c – Fm9 – Dm7b5 – G#13 – C#Maj7 – C7b5 – Gm11 – G7b9 – C#9 – C7b9 – Fm – Gm7 – C7 – C7#5 – Fm/Bb – FmMaj7 – D#m9 – G#7b9 – C#maj9 – A#7b9 – F#maj9 – Dm9 – CMaj7 – Fmaj9 – F#m7 – B7#5.
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 major third), C# to F (ascending major third), F to C# (descending major third), C# to F (ascending major third), F to D (descending minor third), D to G# (ascending tritone), G# to C# (ascending perfect fourth), C# to C (descending half step), C to G (descending perfect fourth), G to G (ascending unison), G to C# (ascending tritone), C# to C (descending half step), C to F (ascending perfect fourth), F to G (ascending whole step), G to C (ascending perfect fourth), C to C (ascending unison), C to F (ascending perfect fourth), F to F (ascending unison), F to D# (descending whole step), D# to G# (ascending perfect fourth), G# to C# (ascending perfect fourth), C# to A# (descending minor third), A# to F# (descending major third), F# to D (descending major third), D to C (descending whole step), C to F (ascending perfect fourth), F to F# (ascending half step), F# to B (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 B to F by tritone.
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.
