Harker student singers were visited by Emily Sinclair, head of the voice area at the University of California Santa Cruz, and an accomplished professional singer and vocal teacher. Sinclair, who has performed with the San Francisco Choral Society and the Littleton Symphony, had students sing a piece of their choice, after which she offered feedback on interpretation, technique and expression. As the students listened to and incorporated her advice, she noted the improvement in their performance, for which the students were very appreciative!
