Águas de Março in B

Águas de Março in B

Jobim compuso 'Águas de Março' en 1972 y fue votada repetidamente como la mayor canción brasileña de todos los tiempos. La letra es un torrente de imágenes (un palo, una piedra, el fin del camino) que simbolizan el ciclo eterno de las aguas. La armonía de Do mayor es sencilla — C–Am–F–G7 — pero el ritmo de samba y la melodía la convierten en obra maestra.

Águas de Março 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 E (descending major third), E to F# (ascending whole step), F# to B (ascending perfect fourth), B to C# (ascending whole step). The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from C# to B by whole step.

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.
