Libertango in B

Libertango in B

Astor Piazzolla compuso 'Libertango' en 1974 en Milán y publicó el álbum homónimo; es el tango más grabado del siglo XX, con versiones de Carlos Santana, Yo-Yo Ma, Grace Jones y miles de otros artistas. El título une 'libertad' y 'tango': Piazzolla liberó el tango de los salones y lo llevó a las salas de concierto. El ostinato Am-Dm-E7 es hipnótico, pulsante, imposible de ignorar — el tango como organismo vivo que no para.

Libertango in B

B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

The bass line moves through B to E (ascending perfect fourth), E to F# (ascending whole step), F# to G (ascending half step), G to A (ascending whole step), A to F# (descending minor third). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from F# to B by perfect fourth.

Scales for Improvisation

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