According to "Rolling Stone", "Her mastery of melisma, the fluttering strings of notes that decorate songs like "Vision of Love", inspired the entire "American Idol" vocal school, for better or worse, and virtually every other female R&B singer since the Nineties." In 2008, Jody Rosen of "Slate" wrote of Carey's influence in modern music, calling her the most influential vocal stylist of the last two decades, the person who made rococo melismatic singing. Rosen further exemplified Carey's influence by drawing a parallel with American Idol, which to her, "often played out as a clash of melisma-mad Mariah wannabes. And, today, nearly 20 years after Carey's debut, major labels continue to bet the farm on young stars such as the winner of Britain's X Factor show, Leona Lewis, with her Generation Next gloss on Mariah's big voice and big hair." "New York Magazine"s editor Roger Deckker further commented that "Whitney Houston may have introduced melisma (the vocally acrobatic style of lending a word an extra syllable or twenty) to the charts, but it was Mariah—with her jaw-dropping range—who made it into America's default sound." Deckker also added that "Every time you turn on American Idol, you are watching her children." As Professor Katherine L. Meizel noted in her book, "The Mediation of Identity Politics in American Idol", "Carey's influence not just stops in the emulation of melisma or her singing amongst the wannabe's, it's also her persona, her diva, her stardom which inspires them... a pre-fame conic look."
