Quién Será (Sway) in A
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 major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through A to E (descending perfect fourth), E 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.
