Quién Será (Sway) in B

Quién Será (Sway) in B

Pablo Beltrán Ruiz compuso 'Quién Será' en 1953 como mambo cubano, y Dean Martin la internacionalizó en 1954 como 'Sway'. Desde entonces ha sido versionada por Michael Bublé, The Pussycat Dolls y docenas de artistas. El patrón i-iv-V7-i en La menor sobre ritmo de mambo es tan hipnótico que baila solo: un standard que navega entre el latin jazz, el pop y el cine.

Quién Será (Sway) 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). The mix of stepwise and leap motion balances smoothness with harmonic drive. When the progression loops, the bass returns from E to B by perfect fourth.

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.
