Chord Diagrams — Quién Será (Sway) in A# (Guitar)

Quién Será (Sway) in A#

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 A#

A# (Bb) major requires barre chords rooted at fret 1 on the A string or fret 6 on the E string. Despite the barre demands, it is a common key in funk, New Orleans R&B, and brass band music. The open D string can ring as the major third for added color. A# is a intermediate-level key on guitar because the open D string is the major 3rd of Bb, adding a bright color if allowed to ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

The bass line moves through A# to F (descending perfect fourth), F to D# (descending whole step). The mix of stepwise and leap motion balances smoothness with harmonic drive. When the progression loops, the bass returns from D# to A# by perfect fourth.

Scales for Improvisation

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