It’s official. New England Conservatory’s heralded El Sistema fellows program, in its fifth year, is ending. NEC President Tony Woodcock said in a letter to staff that the Venezuelan music education program fulfilled its mission of training 50 postgraduate musicians “who are passionate about creating careers . . . that connect music, youth, and social change.” Some next steps: integrate the Sistema ideals into NEC’s curriculum and help the fellows experience other programs in the US.
