Sway (¿Quién Será?) in C#

Sway (¿Quién Será?) in C#

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 C#

C# major (or Db) sits in barre chord territory across the fretboard. Every chord demands precise barring, but the payoff is a bright, crystalline sound a half step above C that cuts through a band mix. C# is a intermediate-advanced-level key on guitar because no open strings fall within the key naturally, so every chord requires full barre technique. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

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

Scales for Improvisation

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