El Preso in B

El Preso in B

Fruko y sus Tesos grabaron 'El Preso' en 1972, una de las canciones de salsa colombiana más escuchadas de todos los tiempos. Joe Arroyo, integrante de la orquesta, dio voz a este relato de un preso que implora justicia. La fusión de cumbias, porros y ritmos afrocaribeños que Fruko desarrolló en Medellín creó la 'salsa caleña', hoy el estilo de salsa más bailado en competencias internacionales.

El Preso 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 F# (descending perfect fourth), F# to E (descending whole step), E to D (descending whole step), D to A (descending perfect fourth). The mix of stepwise and leap motion balances smoothness with harmonic drive. 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.
