En Mi Viejo San Juan in A#

En Mi Viejo San Juan in A#

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 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 G (descending minor third), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to C (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 C to A# by whole step.

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.
