Canto de Ossanha in F

Canto de Ossanha in F

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 F

F major is the gateway to barre chords. While F itself requires a full barre at fret 1, the remaining diatonic chords (C, Dm, Am, G, Bb) mix open and barre shapes. The open high E acts as Fmaj7's seventh, adding unexpected richness. F is a intermediate-level key on guitar because the open high E string is the major seventh of F, creating a lush Fmaj7 resonance even in basic shapes, but the F barre chord itself is the first big hurdle for beginners. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

The bass line moves through F to D# (descending whole step), D# to C (descending minor third), C to A# (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from A# to F by perfect fourth.

Scales for Improvisation

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