En Mi Viejo San Juan in D#
En Mi Viejo San Juan in D#
Noel Estrada compuso 'En Mi Viejo San Juan' en 1943 desde Nueva York, añorando Puerto Rico. Es el himno sentimental del pueblo puertorriqueño en la diáspora: cada boricua que ha salido de la isla la lleva en el corazón. Marc Anthony, Gilberto Monroig y Lola Flores la interpretaron; hoy es el vals-bolero que define la identidad puertorriqueña tanto en la isla como en el continente.
En Mi Viejo San Juan 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 C (descending minor third), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to F (descending minor 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 D# by whole step.
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.
