Bruno Maderna (21 April 1920 – 13 November 1973) was an Italian conductor and composer.
Bruno Maderna was born Bruno Grossato in Venice but later decided to take the name of his mother, Caterina Maderna. At the age of four he began studying the violin with his grandfather. ‘My grandfather thought that if you could play the violin you could then do anything, even become the biggest gangster. If you play the violin you are always sure of a place in heaven.’ As a child he played several instruments (violin, drums and accordion) in his father's small variety band. A child prodigy, in the early thirties he was not only performing violin concertos, he was already conducting orchestral concerts: first with the orchestra of La Scala in Milan, then in Trieste, Venice, Padua and Verona.
Orphaned at the age of four, Maderna was adopted by a wealthy woman from Verona, Irma Manfredi, who saw that he received a solid musical education. Later after taking private lessons in harmony and composition with Arrigo Pedrollo (1935–37) he studied with composition with Alessandro Bustini at the Rome Conservatory (1937–40).
After Rome he returned to Venice, where he attended the advanced course for composers (1940–42) organised by Gian Francesco Malipiero at the Benedetto Marcello Conservatory (his Concerto for Piano and Orchestra dates from this time). He also studied conducting with Antonio Guarnieri at the Accademia Chigiana in Siena (1941) and Hermann Scherchen in Venice (1948). The meeting with Scherchen was fundamental to Maderna. Through him he discovered twelve-tone technique and the music of the Second Viennese School.
During the Second World War he took part in the partisan resistance. From 1948 to 1952 he taught music theory at the Venice Conservatory. During this period he collaborated with Malipiero on critical editions of Italian early music. Fellow composers he met at this time included Luigi Dallapiccola and, at the Internationale Ferienkurse für Neue Musik, Boulez, Messiaen, Cage, Pousseur, Nono and .
