Oblivion in A#
Oblivion in A#
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 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 C (ascending whole step), C to F (ascending 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.
