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 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 A (ascending perfect fourth), A to B (ascending whole step), B to D (ascending minor third), D to D (ascending unison), D to F# (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 F# 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.
