Sway (¿Quién Será?) in G#

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 G#

G# major (or Ab) lives at fret 4 on the low E string. All chords require barre technique, making it less common in guitar-centric songwriting but standard in piano-driven pop. Guitarists often use a capo to access friendlier shapes. G# is a intermediate-advanced-level key on guitar because the open G string is a half step below the root, creating dissonance — avoid letting it ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

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

Scales for Improvisation

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