Sway (¿Quién Será?) in D

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 D

D major is one of guitar's most resonant keys. The open D string acts as a droning root, and the open A string provides the fifth. This gives D-based strumming a wide, ringing quality that flatpicks and fingerpicks love. D is a beginner-level key on guitar because the open D and A strings provide a powerful bass foundation, and the open high E is the 2nd scale degree adding brightness. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

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

Scales for Improvisation

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