El Preso in A

El Preso in A

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 A

A major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through A to E (descending perfect fourth), E to D (descending whole step), D to C (descending whole step), C to G (descending perfect fourth). The mix of stepwise and leap motion balances smoothness with harmonic drive. 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.
