Desafinado in B

Desafinado in B

Jobim y Newton Mendonça escribieron 'Desafinado' en 1958 como manifiesto humorístico de la bossa-nova. La letra dice 'si você disser que eu desafino amor' —si me dices que desafino, amor— respondiendo a los críticos que no entendían las disonancias del nuevo estilo. Stan Getz y João Gilberto la grabaron en 1962 y ganaron el Grammy. La modulación cromática en el puente es uno de los momentos más elegantes de la bossa.

Desafinado 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 C (ascending tritone), C to A (descending minor third), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to G (ascending unison), G to F# (descending half step), F# to B (ascending perfect fourth), B to E (ascending perfect fourth). A half-step bass movement creates a strong leading-tone pull that demands resolution. 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 E to B by perfect fourth.

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.
