Desafinado (meaning “slightly out of tune”) is one of Tom Jobim’s most famous pieces. It’s his musical answer to critics who couldn’t really get used to the sound of bossa nova.
Joao Gilberto - Bossa Nova Chords
Right at the beginning you will find a typical Joao Gilberto chord: the DMaj7 chord with F# (i.e. the third of the chord) in the bass. From there, a skilful voice leading through the harmonies of Desafinado begins.
For example, observe the hidden melody line within the first three chords (DMaj7 – E7 – Em7):
- The note A (the fifth of DMaj7) is lowered a semitone to…
- …G# (the third of E7) and again lowered a semitone to…
- …G, the minor third of E minor7.
These Guide Tone Lines give the harmonic progression structure and it is worthwhile to work on them in your guitar playing. As in this example, it is often the middle voices that develop a life of their own between the bass and melody voices.
The chords in bars 6-8 are typical of the bossa nova style:
The diminished chord F°7(b13) is as a chromatic passing chord between Em7 and the following II-V-cadence starting with F#m7b5.
The second half of the first part begins with an E-Minor 7th chord (in this case a nice voicing with the option note F#, i.e. the ninth). Now comes an unusual compositional trick: the harmonies are directed to the key of Bb-Major via the intermediate dominant F#7. One would normally expect the parallel minor chord of Bb-Minor here, but Tom Jobim manages to incorporate this unusual key change almost effortlessly. Two more intermediate dominants follow: B7(b9) leads to E7(9).
Before it goes into the repetition, the composer has one more beautiful chord up his sleeve. At first glance, the EbMaj7 chord is unusual in the key of D major. However, it is a usual harmonic suspension in jazz to insert the Major7-chord of the diminished second degree before the return to the tonic.
Up next is a repetition of the first part and then a long second part in which there are two more key changes, many secondary dominants and other beautiful chords to discover.
