Samba de Orfeu in B

Samba de Orfeu in B

Luiz Bonfá compuso este samba exuberante para 'Orfeu Negro' (1959). El movimiento Dmaj7→Dm6 al final de A — mayor a menor con la misma fundamental — es el giro melancólico que define el film. Comparte el ADN de 'Manhã de Carnaval' pero en mayor y a tempo de samba, festivo y luminoso.

Samba de Orfeu 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 G# (descending minor third), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to E (descending whole step), E to E (ascending unison), E to E (ascending unison), E to E (ascending unison). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from E 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.
