Songs in the Key of Life is the eighteenth studio album by American singer, songwriter and musician Stevie Wonder. A double album, it was released on September 28, 1976, by Tamla Records, a division of Motown. It was recorded primarily at Crystal Sound studio in Hollywood, with some sessions recorded at the Record Plant in Hollywood, the Record Plant in Sausalito, and The Hit Factory in New York City; final mixing was conducted at Crystal Sound. The album has been regarded by music journalists as the culmination of Wonder's "classic period" of recording.

Stevland Hardaway Morris, known professionally as Stevie Wonder, is an American-Ghanaian singer-songwriter, musician, and record producer. He is credited as a pioneer and influence by musicians across a range of genres that include R&B, pop, soul, gospel, funk, and jazz. A virtual one-man band, Wonder's use of synthesizers and other electronic musical instruments during the 1970s reshaped the conventions of contemporary R&B. He also helped drive such genres into the album era, crafting his LPs as cohesive and consistent, in addition to socially conscious statements with complex compositions. Blind since shortly after his birth, Wonder was a child prodigy who signed with Motown's Tamla label at the age of 11, where he was given the professional name Little Stevie Wonder.
