Sway (¿Quién Será?) in F

Pablo Beltrán Ruiz compuso 'Quién Será' en 1953 para el cantante Acerina. Dean Martin la grabó en inglés como 'Sway' en 1954 y llegó al Top 10 en EE.UU. Michael Bublé la revivió en 2003. El mambo cha-cha festivo con su ostinato de Am-E7 es uno de los ritmos latinos más conocidos en el mundo anglosajón, y 'Sway' figura en innumerables bandas sonoras de Hollywood.

Sway (¿Quién Será?) 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 C (descending perfect fourth), C to A# (descending whole step), A# to G# (descending whole step), G# to D# (descending perfect fourth), D# to F (ascending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from F to F 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.
