How do they do it? Some of the biggest music stars ever never knew how to read or write sheet music, but it didn't matter....you may think that's believable about people like Elvis, or even Jimi Hendrix, who seemed to exist on brilliant improvisation, but Michael Jackson? Slash of Guns n Roses? Paul McCartney, who wrote some of the most elaborate, memorable pop songs of all time? In McCartney's case, he says none of the Beatles knew how to read music when they got together, but they knew how to play chords, and that got them thru...Slash says he hears something in his head, and tries to make what he hears come out his hands to the guitar....word is Michael Jackson never learned to read music either. He'd just sing out into a tape recorder whatever he was thinking musically...so here's more about the stars that rock the music world without knowing how to read it: Dylan, Prince, Eddie Van Halen (he says he faked it with his piano teacher when he was a kid), Eric Clapton and more.
