He was a very prolific composer who left a great body of work, not just, as most people think, The Gir... and not just Bossa Nova.
Some of my favorites, in no particular order
1.Chovendo Na Roseira aka Double Rainbow aka Children's Games aka It's Raining in the Rose Garden in 3/4 time with two measures of 2/4
2. Mojave, another 3/4 that I would put up against any Jazz waltz
3. Brigas Nunca Mais (Fighting Never More), sublime harmony matched with a beautiful melody
4. Caminhos Cruzados
5. Ligia
I could go on...
In some of his songs, Jobim possessed a special quality of finding a certain sequence of notes that, once you heard them as a riff or motif, they stuck in your head for days at a time: the beginning sections to Agua de Beber, Ela E Carioca and Samba do Aviao are perfect examples of this.
