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 (Eb) requires barre shapes rooted on the 6th and 5th strings. It is a favorite key for horn players, so guitarists encounter it in funk and soul bands. Using barre chords at frets 1, 3, and 6 covers the primary shapes. D# is a intermediate-advanced-level key on guitar because no standard open strings match this key's chord tones. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
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.
