Chan Chan in A#

Chan Chan in A#

Francisco Repilado, 'Compay Segundo', compuso 'Chan Chan' alrededor de 1987. Se hizo mundialmente famosa como la canción de apertura del disco 'Buena Vista Social Club' (1997) producido por Ry Cooder y que ganó el Grammy. La película de Wim Wenders llevó el son cubano a audiencias globales. El ostinato de F-Dm-Bb-C7 y el ritmo de son montuno hace de esta canción ideal para aprender el estilo cubano clásico.

Chan Chan 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 D# (descending major third), D# to F (ascending whole step), F to C (descending perfect fourth), C to G (descending perfect fourth). 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.
