O Pato (The Duck) in F

Jaime Silva's 1960 samba propels through D major cycles before opening into a long through-composed section in G major — rich with chromatic mediant movement (Gmaj7–Gm6–F#m7–D9) and a classic Em–B7 inner-voice cycle. Jon Hendricks's English lyric turned it into a jazz vocal standard.

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 G (ascending whole step), G to G (ascending unison), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to C (descending perfect fourth), C to C (ascending unison), C to C (ascending unison), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to A# (ascending unison), A# to C (ascending whole step), C to F (ascending perfect fourth), F to F (ascending unison), F to A# (ascending perfect fourth), A# to A# (ascending unison), A# to A (descending half step), A to G (descending whole step), G to D (descending perfect fourth). 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 F by minor third.

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.
