Tú Mi Delirio in F

Tú Mi Delirio in F

Tú Mi Delirio in F — César Portillo de la Luz's timeless bolero. The Bebop Major and Major Pentatonic scales work beautifully over these romantic changes. Chords: F – Fmaj7 – Gm7 – C7 – Dm7 – A# – A#m – A7.

Tú Mi Delirio 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 F (ascending unison), F to G (ascending whole step), G to C (ascending perfect fourth), C to D (ascending whole step), D to A# (descending major third), A# to A# (ascending unison), A# to A (descending half step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from A to F by major third.

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.
