Cambalache in A#

Cambalache in A#

Enrique Santos Discépolo compuso 'Cambalache' en 1934, el año que Argentina caía en el abismo político. La letra es el diagnóstico más brutal de la modernidad que el tango produjo: 'el mundo fue y será una porquería / ya lo sé / en el quinientos seis / y en el dos mil también'. El cambalache es el almacén de ropa usada, la metáfora de una sociedad que mezcla lo sagrado con lo profano. El Bdim7 —el vii°7 de C menor— es la tensión irresuelble que el siglo XX nunca cerró.

Cambalache 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 A (descending half step), A to F (descending major third), F to D# (descending whole step), D# to C# (descending whole step), C# to G# (descending perfect fourth). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from G# 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.
