NEW YORK (AP) _ She's not the first person to waste violin lessons.

Madonna has decided not to play the lead in ``50 Violins,'' a movie about an inner-city music teacher, Miramax said Tuesday.

Wes Craven, the film's director, said the problem was ``genuine mutual creative differences.''

Madonna's spokeswoman, Liz Rosenberg, did not immediately return a call Tuesday.

Madonna spent three months learning the violin so she could play the role of Roberta Tzavaris, who taught kids in East Harlem, Daily Variety said.
