When playing ‘Girl from Ipanema’ the chords are: I maj 7, II 7, ii7, then what? I# maj 7? Then back to I maj 7. Then it modulates three times for the middle section. How does the chord numbering system deal with moduation? Tricky stuff this Latin Jazz but it sounds so great.
This song has become a standard and epitomises the Bossa Nova rhythm. It was sung, in Portugese and then English, by Astrud Gilberto. Basia, from Matt Bianco, sung a tribute to her. The guitar style in both songs looks effortless, the hand moving up and down the frets playing the complex chords. if were a guitarist, then I’d want to play it.
bII7 is a good bet. Flattened second or sharpened tonic. I just used this song as an example. How passing chords, not in the tonic key, are represented is what I’m trying to find out.
