Quién Será (Sway) in D

Quién Será (Sway) in D

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 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). The mix of stepwise and leap motion balances smoothness with harmonic drive. When the progression loops, the bass returns from G to D by perfect fourth.

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.
