Sabiá in A

Sabiá in A

Tom Jobim y Chico Buarque compusieron 'Sabiá' en 1968 y ganó el Festival Internacional da Canção en Brasil —una victoria polémica que el público abucheó porque prefería a Caetano Veloso. Un sabiá es un tordo americano, ave símbolo de la añoranza del Brasil distante. La modulación Ebm7-Ab7-Dbmaj7 en la sección A —un ii-V-I que baja un semitono al bVI— es el giro jobimiano por excelencia: una caída armónica que lleva la melancolía exactamente adonde la letra la necesita.

Sabiá in A

A major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through A to B (ascending whole step), B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to C# (ascending tritone), C# to F# (ascending perfect fourth), F# to C# (descending perfect fourth), C# to F# (ascending perfect fourth). 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 F# to A by minor third.

Scales for Improvisation

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