Canto de Ossanha in B
Canto de Ossanha in B
Baden Powell y Vinícius de Moraes dedicaron este afro-samba (1966) a Ossanha, orixá de las plantas medicinales y los engaños en el Candomblé. La letra — 'Homem que diz sou livre, livre não está' — es una advertencia. El ostinato Em–D es primo hermano de Berimbau, igualmente hipnótico, con el B7 como inevitable dominante del destino.
Canto de Ossanha 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 A (descending whole step), A to F# (descending minor third), F# to E (descending whole step). 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.
