Williams College held the annual All-Night Marathon of Voices on 19 January. Shortly after sundown Ellery Galvin led members from the college Concert Choir in a performance of Tone (excerpt). Three groups of singers sustained a single tone seamlessly for 10 minutes. The groups were positioned around the pews so the sound slowly shifted location but maintained a constant volume. The piece requires careful coordination of breath and Ellery led the singers through a beautiful performance. A few minutes into the tone a strong acoustic resonance arose and accompanied the sound of the voices. Thanks to Ellery and the singers! There was a lovely atmosphere with varied stylistic contributions from members of the community.
