Por una Cabeza in B

Por una Cabeza in B

Por una Cabeza in B — Carlos Gardel / Alfredo Le Pera's tango classic. Bebop Major and Major Pentatonic scales bring out the bold, energetic spirit of these changes. Chords: B – F#7 – G#m – E – D#7 – C#m.

Por una Cabeza 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 F# (descending perfect fourth), F# to G# (ascending whole step), G# to E (descending major third), E to D# (descending half step), D# to C# (descending whole step). 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 C# to B by whole step.

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.
