Plástico in A#
Plástico in A#
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 A#
A# (Bb) major requires barre chords rooted at fret 1 on the A string or fret 6 on the E string. Despite the barre demands, it is a common key in funk, New Orleans R&B, and brass band music. The open D string can ring as the major third for added color. A# is a intermediate-level key on guitar because the open D string is the major 3rd of Bb, adding a bright color if allowed to ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
Voice Leading
The bass line moves through A# to F (descending perfect fourth), F to D# (descending whole step), D# to C# (descending whole step), C# to G# (descending perfect fourth), G# to F# (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from F# to A# by major third.
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.
