Plástico in F

Plástico in F

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 F

F major is the gateway to barre chords. While F itself requires a full barre at fret 1, the remaining diatonic chords (C, Dm, Am, G, Bb) mix open and barre shapes. The open high E acts as Fmaj7's seventh, adding unexpected richness. F is a intermediate-level key on guitar because the open high E string is the major seventh of F, creating a lush Fmaj7 resonance even in basic shapes, but the F barre chord itself is the first big hurdle for beginners. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

The bass line moves through F to C (descending perfect fourth), C 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 F by major third.

Scales for Improvisation

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