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 major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through A to B (ascending whole step), B to E (ascending perfect fourth), E 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.
