Obsesión in F: Pedro Flores's bolero in minor. Dorian and Harmonic Minor scales capture the emotion of these heartfelt changes. Chords: Fm7 – Gm7b5 – C7(#9) – A#m7 – D#7 – G#Maj7 – C#Maj7 – G7(#9) – Adim – G7(#9b5) – C7.

Obsesión in 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 G (ascending whole step), G to C (ascending perfect fourth), C to A# (descending whole step), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to C# (ascending perfect fourth), C# to G (ascending tritone), G to A (ascending whole step), A to G (descending whole step), G to C (ascending perfect fourth). 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 F by perfect fourth.

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.
