Osesp Youth Choir was created in 2004 to cater for young people who no longer fit into the Children's Choir but who are not yet ready to join a professional artistic ensemble. The participants, aged between 13 and 17, take introductory music lessons, solfeggio and aural training lessons, as well as prosody and diction classes. They explore a complex and eclectic repertoire that is performed at Sala São Paulo and elsewhere. The ensemble is conducted by Marcos Thadeu.
