Plástico in E

Plástico in E

Rubén Blades y Willie Colón escribieron 'Plástico' en el álbum 'Siembra' (1978), el LP de salsa más vendido de la historia. La letra critica al latinoamericano que abandona su identidad para imitar al consumidor anglosajón: 'son gente plástica / de caras bonitas / de idioma confuso'. El álbum 'Siembra' plantó la semilla de la salsa intelectual y socialmente comprometida. El Bm-F#7 es la salsa en su versión más oscura y comprometida: sin concesiones al baile fácil.

Plástico in E

E major is arguably guitar's most powerful key. The open low E and high E strings ring sympathetically as the root, while the open B provides the fifth. This triple reinforcement gives E-based riffs and chords unmatched depth and volume. E is a beginner-level key on guitar because both the low E and high E strings ring as the root, and the open B is the fifth — three open strings reinforce the tonic chord. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through E to B (descending perfect fourth), B to A (descending whole step), A to G (descending whole step), G to D (descending perfect fourth), D to C (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from C to E by major third.

Scales for Improvisation

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