British guitarist/vocalist Eric Clapton, “with a band of stellar musicians that included the late Duane Allman, went into Florida’s Criteria Studios to record what would become one of the great classic albums of all time, Layla and Other Assorted Love Songs,” (American Songwriter). “With its standout track ‘Layla,’ the album became a timeless record that helped determine the direction of 1970s rock guitar, performed by a band called Derek and the Dominos, as Clapton didn’t want to use his name for the marquee value.
‘Layla’ was a song Clapton wrote, with Dominos drummer Jim Gordon, about his forbidden love for the wife of his close friend George Harrison (she eventually became Clapton’s wife) … The album might have done big business had Clapton been up front about being the big name in the group, but instead, it stalled on the charts. When the edited version of ‘Layla’ was released to radio as a single in 1972, it did fairly well, but by this time Allman was dead and the band had broken up.” But in 1992, “propelled by ‘Layla’ and ‘Tears in Heaven,’ Unplugged became Clapton’s biggest selling-album, as well as one of the biggest-selling live albums in history, with a purported 26 million copies sold. ‘Layla’ won a Grammy, more than two decades after it was originally recorded, for Best Rock Song …”
After the iconic intro states the guitar-driven hook, a surprising downward half-step key change hits as verse 1 begins (0:24). We’re thrown off-kilter by a bar of 2/4 among the track’s overall 4/4 meter at 0:22, immediately preceding the modulation. The key reverts up a half-step for the first chorus, and the pattern continues from there. At 3:11, an instrumental section featuring piano drops a full step as it morphs into a more peaceful major key, taking up the second 50% of the track.
