Composed mostly of teenagers signed straight out of inner-city high schools, girl groups were designed primarily to satisfy teenagers’ need for a “beat they could dance to and performers they could identify with.” Despite the patronizing marketing that accompanied this enterprise, most girl groups achieved substantial success because their music reflected typical adolescent sentiments of vulnerability, solidarity, and longing – characteristics that the Beatles were able to incorporate into their own music by covering girl group songs and adopting similar musical tropes.
