"Stardust" is a jazz song composed by American singer, songwriter and musician Hoagy Carmichael. Now considered a standard and part of the Great American Songbook, the song has been recorded over 1,500 times either as an instrumental or vocal track, featuring different performers. During his time attending Indiana University, Carmichael developed a taste for jazz. He formed his own band and played at local events in Indiana and Ohio. Following his graduation, Carmichael moved to Florida to work for a law firm. He left the law sector and returned to Indiana, after having learned of the success of one of his compositions. In 1927, after leaving a local university hangout, Carmichael started to whistle a tune that he later developed further. When composing the song, he was inspired by the end of one of his love affairs, and on the suggestion of a university classmate, he decided on its title. The same year, Carmichael recorded an instrumental version of the song for Gennett Records.
