 In 1895, he composed his first opera, "Martin Pas", which has since been lost.Now in his teen years, Varèse, influenced by his father, an engineer, enrolled at the Polytechnic of Turin and started studying engineering, as his father disapproved of his interest in music and demanded an absolute dedication to engineering studies.This conflict grew greater and greater, especially after the death of his mother in 1900, until in 1903 Varèse left home for Paris.
