Qué Rico el Mambo in B
Qué Rico el Mambo in B
Dámaso Pérez Prado lanzó 'Qué Rico el Mambo' en 1949 y desencadenó la mambo-manía que conquistó Estados Unidos en los 50: El Rey del Mambo llenaba el Palladium de Nueva York y vendía millones de discos. La progresión Eb-Bb7 es la arquitectura más básica del mambo: potente, repetitiva, diseñada para el cuerpo. El giro Ab→Abm en la sección B —préstamo del modo paralelo— es el único adorno armónico que Pérez Prado necesitaba para crear drama.
Qué Rico el Mambo 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 E (ascending unison). The predominantly stepwise bass motion creates smooth, connected voice leading. 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.
