La Comparsa in B

La Comparsa in B

Lecuona compuso 'La Comparsa' (1929) para piano, evocando la procesión del carnaval habanero. La estructura ABA — menor→mayor→menor — captura la dualidad del carnaval: alegría y melancolía simultáneas. La sección B en Mi mayor es de una luminosidad repentina que contrasta con el modo menor del A, como si la comparsa pasara frente a un farol.

La Comparsa 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 E (ascending perfect fourth), E to F# (ascending whole step), F# to B (ascending perfect fourth), B to E (ascending 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 E to B by perfect fourth.

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.
