Plástico in G

Plástico in G

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 G

G major is the singer-songwriter's key. The open G, B, and D strings spell out the full G major triad with zero fretting. Add the open high E for a Gadd6 shimmer. Nearly every diatonic chord (Em, Am, C, D) has a comfortable open voicing. G is a beginner-level key on guitar because the open G, B, and D strings form a complete G major triad without fretting a single note, and the open low E adds a rich 6th color. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

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

Scales for Improvisation

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