The (Istiklal) street version of Antonio Carlos Jobim’s ‘Desafinado,’ a popular bossa nova tune, played on the trumpet. Jobim helped define the Brazilian bossa nova movement in the early 1960s. Bossa nova, a combination of the samba and jazz, became internationally popular, and is still part of the jazz ‘standards’ library. Jobim’s compositions have been performed and recorded many, many times. Here is a performance of this song by João Gilberto, the other main bossa nova innovator.
The cümbüş (“joomboosh” – close enough pronunciation) is a Turkish stringed instrument that is kind of a cross between an ud and a banjo. This is an older gentlemen playing cümbüş at night on Istiklal Avenue.
