Only Trust Your Heart is a jazz standard composed by Benny Carter with lyrics by Sammy Cahn. It was first released in October 1964 by The New Stan Getz Quartet featuring Astrud Gilberto, and it was commissioned for the TV movie The Hanged Man which premiered on November 18, 1964. The tune is performed in English and is noted for its flowing bossa nova - inflected jazz style. It is not to be confused with a separate 1957 Sammy Cahn lyric to a different song with the same title and music by Nicholas Brodszky. Over the years it has been widely covered, and publishers offer easy jazz ensemble and big band arrangements that capture its approachable Brazilian-influenced vibe.
