“Stevie Wonder turned 18 years old during 1968. Since the age of 12 he had been producing hits and had become one of the most commercially successful artists for the Motown label,” (Seattle Post Intelligencer). “Motown was known for the control of its artists and their output. Wonder, however, was beginning to establish his own identity and take control of his career. His contract with the label was coming to an end and Motown desperately wanted to sign him to a new one and so began giving him leeway in the producing and recording of his albums.
Wonder co-wrote or wrote eight of the 12 tracks on For Once In My Life, plus took production credit for the first time … It was one of the four compositions credited to other songwriters that became the album’s title track and biggest hit. Ron Miller and Orlando Murden wrote ‘For Once In My Life’ for the label and not specifically for Wonder. His version, however, would become the definitive one. Artists such as The Temptations and Tony Bennett would record the song in a ballad style. Wonder would change it into an exuberant, up-tempo, and soulful classic. It reached #2 on the Billboard Pop Singles chart and #1 on the Rhythm and Blues chart.”
“Wonder and his producer, Hank Cosby … sped it up, gave it a string arrangement, complete with an animated piccolo motif, and turned it into his biggest hit to date, kept from the US #1 spot only by his fellow Motowner, Marvin Gaye,” (Yahoo). “Wonder’s probable lack of enthusiasm at singing someone else’s song is concealed by his exuberant performance.” The grand scale of the tune’s arrangement, coupled with Stevie’s overflowing energy, would never hint at its short run time of only 2:49. But with apparently astounding precision, the tune’s half-step key change is situated at almost exactly the half-way mark (1:25).
