Musically, JoJo is considered to be primarily a pop and R&B artist; however, the majority of her singles tend to lean more-so towards the former as a marketing tool. "Prefix"'s Norman Meyers observed that "As an adolescent white girl singing mainstream R&B, her singles have leaned toward pop to snag sales ... But the list of producers on "The High Road ..." shows that Jojo is more concerned with harder beats and soulful sounds." JoJo is a soprano and her singing voice has been widely acclaimed by music critics, one of whom ranked it among "the best in the game", while her R&B recordings have been compared to the likes of R&B singers Brandy and Monica. Describing her as a "vocal phenom", "Entertainment Weekly"s Leah Greenblatt enthused that JoJo is "capable of Mariah Carey-style upper-register flourishes". Vocally, critics frequently draw comparisons between JoJo and singers Kelly Clarkson and Beyoncé, while "Slant Magazine"'s Sal Cinquemani remarked that the singer "could very well be the next Teena Marie".
