Narcís Bonet was born in Barcelona on January 22, 1933. He is the son of the architect Lluís Bonet Garí who built the façade of Gaudí’s Basillica and Expiatory Church of the Holy Family. His brother, Jordi Bonet Armengol, is the current chief architect at the Basilica.
Narcís Bonet gave his first public performance at the Palau de la Música Catalana in Barcelona at the age of 13, both as composer and pianist. In 1948, Ekitay Ahn, the conductor of the Majorca Symphony Orchestra commissioned his first symphonic work, La vaca cega, that was performed in the main theatre.
After studying in Barcelona with Eduard Toldrá, Joan Massiá, Joan Llongeres, Emili Pujol and Lluís M. Millet, he moved to Paris to continue his musical studies with Nadia Boulanger and later studies in conducting with Igor Markevitch.
