Bossa nova
Bossa nova is a hybrid form based on the samba rhythm, but influenced by European and American music from Debussy to US jazz. Bossa nova originated in the 1950s, largely from the efforts of Brazilians Antonio Carlos Jobim and João Gilberto. Its most famous song is arguably "The Girl from Ipanema" sung by Gilberto and his wife, Astrud Gilberto. While the musical style evolved from samba, it is more complex harmonically and less percussive. Bossa nova emerged primarily from the upscale beachside neighborhoods of Rio de Janeiro as opposed to samba's origins in the favelas of Rio. Certain similar elements were already evident, even influencing Western classical music like Gershwin's Cuban Overture which has the characteristic 'Latin' clave rhythm. The influence on bossa nova of jazz styles such as cool jazz is often debated by historians and fans, but a similar "cool sensibility" is apparent.
