Cuando Vuelva a Tu Lado in A#
Cuando Vuelva a Tu Lado in A#
María Grever, primera compositora mexicana de fama internacional, escribió 'Cuando Vuelva a Tu Lado' en 1934. En inglés se llamó 'What a Difference a Day Makes' y Dinah Washington la convirtió en un clásico del R&B en 1959, ganando el Grammy. Es uno de los pocos estándares latinoamericanos que cruzó completamente al canon del jazz anglosajón.
Cuando Vuelva a Tu Lado in A#
A# (Bb) major requires barre chords rooted at fret 1 on the A string or fret 6 on the E string. Despite the barre demands, it is a common key in funk, New Orleans R&B, and brass band music. The open D string can ring as the major third for added color. A# is a intermediate-level key on guitar because the open D string is the major 3rd of Bb, adding a bright color if allowed to ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
Voice Leading
The bass line moves through A# to F (descending perfect fourth), F to A# (ascending perfect fourth), A# to C (ascending whole step), C to D# (ascending minor third), D# to D# (ascending unison), D# to G (ascending major third). The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from G to A# by minor third.
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.
