As Artistic Director of Indianapolis Symphonic Choir, Eric Stark speaks candidly about his choir's role in the upcoming famous one-act ballet Daphnis et Chloé by Maurice Ravel. The wordless voices in the score add another dimension as they are used like instruments in the piece. Stark says that even though the score is "ravishingly beautiful," it's a highly demanding piece to orchestrate. Krzysztof Urbański, who will be conducting the Indianapolis Symphony Orchestra's role in the piece, couldn't agree more. Along with Dance Kaleidoscope's David Hochoy, who is choreographing the performance, Urbański and Stark are up for the challenge. Listen and watch how the Indianapolis Symphonic Choir creates hauntingly melodic and harmonic "sounds" for Ravel's mastery of orchestration -- some with open mouths and other with lips pursed.
