Samba Do Avião

Eight diminished chords out of fifty-eight. That's the highest concentration of diminished chords in this library, and they show up in the second bar, alternating with the home chord.

The diminished is the chord most players guess at. There are genuinely different readings for it, and the choice changes the character of the whole phrase — from elegant to tense, from romantic to dense. Nine tonal centres across six sections.
