Sway (¿Quién Será?) in B

Sway (¿Quién Será?) in B

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 B

B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

The bass line moves through B to F# (descending perfect fourth), F# to E (descending whole step), E to D (descending whole step), D to A (descending perfect fourth), A to B (ascending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from B to B by unison.

Scales for Improvisation

B 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, B Mixolydian adds the flat seventh for an authentic blues-rock edge.
