Cambalache in B

Cambalache in B

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 B

B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

The bass line moves through B to A# (descending half step), A# to F# (descending major third), F# to E (descending whole step), E to D (descending whole step), D to A (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 A to B by whole step.

Scales for Improvisation

B 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, B Mixolydian adds the flat seventh for an authentic blues-rock edge.
