Desafinado in A
Desafinado in A
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 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 B (ascending unison), B to E (ascending perfect fourth), E to A# (ascending tritone), A# to G (descending minor third), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to F (ascending unison), F to E (descending half step), E to A (ascending perfect fourth), A to D (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 D to A by perfect fourth.
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.
