Oblivion in G#
Oblivion in G#
Astor Piazzolla compuso 'Oblivion' en 1982 para la película italiana 'Enrico IV' de Marco Bellocchio. Es su obra más escuchada en el mundo clásico: Miles Davis, Yo-Yo Ma y la Royal Philharmonic la han grabado. 'Oblivion' (olvido) capta en D menor el estado de suspensión entre la memoria y la pérdida. El Em7b5-A7 —el ii°-V de D menor— es la cadencia más patética del tango: no resuelve, pregunta. La melodía se niega a llegar a la tónica demasiado pronto.
Oblivion in G#
G# major (or Ab) lives at fret 4 on the low E string. All chords require barre technique, making it less common in guitar-centric songwriting but standard in piano-driven pop. Guitarists often use a capo to access friendlier shapes. G# is a intermediate-advanced-level key on guitar because the open G string is a half step below the root, creating dissonance — avoid letting it ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
Voice Leading
The bass line moves through G# to A# (ascending whole step), A# to D# (ascending perfect fourth), D# to C# (descending whole step), C# to B (descending whole step), B to F# (descending perfect fourth), F# to E (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from E 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.
