Vitamin C, “Graduation (Friends Forever)” (2000)
Black Eyed Peas, “Where Is The Love” (2003)
Belle and Sebastian, “Get Me Away From Here, I’m Dying” (1998)

“Graduation,” the biggest hit of American pop singer Vitamin C, is often played at high school graduations. “Where Is The Love” is the Black Eyed Peas’ first top-ten hit, featuring additional vocals by Justin Timberlake. Similar to pieces in continuous variation form (from the Baroque period and beyond), both of these songs feature a single harmonic progression that repeats throughout.
