Por una Cabeza in C

Por una Cabeza in C

Carlos Gardel y Alfredo Le Pera compusieron 'Por una Cabeza' en 1935 para la película 'Tango Bar'. Es el tango más reconocible del mundo no rioplatense: 'Scent of a Woman' (Al Pacino, 1992) lo inmortalizó en Hollywood y desde entonces es sinónimo de seducción y elegancia argentina. La melodía en Do mayor, con ese bandoneón que suspira, ha cruzado todos los idiomas y todas las pistas de baile del planeta.

Por una Cabeza in C

With no sharps or flats, C major is the theoretical home base on guitar. The open G, B, and high E strings all belong to the C major chord, creating natural sustain. C is a beginner-level key on guitar because the open B and high E strings ring within the scale, and every basic chord uses familiar open shapes. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through C to G (descending perfect fourth), G to A (ascending whole step), A to F (descending major third), F to E (descending half step), E to D (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 D to C by whole step.

Scales for Improvisation

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