A Banda in A#

A Banda in A#

Chico Buarque de Hollanda compuso 'A Banda' en 1966 con 22 años y ganó el II Festival da Canção Brasileira empatado con 'Disparada' de Geraldo Vandré. La canción cuenta cómo una banda de músicos que pasa por la calle levanta el ánimo de todos los que sufren —el guardia triste, la moça abandonada, la velha com saudades. Es el humanismo musical de Chico en su forma más pura. El puente Gm-D7 introduce la única sombra menor antes de que la banda vuelva al Bb festivo.

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