O Pato (The Duck) in B

O Pato (The Duck) in B

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.

O Pato (The Duck) 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 C# (ascending whole step), C# to C# (ascending unison), C# to F# (ascending perfect fourth), F# to B (ascending perfect fourth), B to F# (descending perfect fourth), F# to F# (ascending unison), F# to F# (ascending unison), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to E (ascending unison), E to F# (ascending whole step), F# to B (ascending perfect fourth), B to B (ascending unison), B to E (ascending perfect fourth), E to E (ascending unison), E to D# (descending half step), D# to C# (descending whole step), C# to G# (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 G# to B by minor third.

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.
