"Desafinado" (Portuguese meaning: out of tune) was composed by Antonio Carlos Jobim. Apparently one of the reasons "Tom" Jobim wrote Desafinado was because he was aware that he was not a good singer, hence Desafinado (Out of Tune) was written. The song begins by him saying "If you say that I sing out of tune my love, know that this immensely hurts me, only privileged people have good ears like yours, I have just what God has given me."

The version by saxophonist Stan Getz (Gayetzky) and Charlie Byrd playing finger style on his classical guitar on the album "Jazz Samba" hit in 1962. The single reached number 15 on the pop chart. This brought bossa nova into the world spotlight.
