In a 2020 video from the National Gallery of Canada, senior curator of contemporary art Josée Drouin-Brisebois talks about Janet Cardiff’s critically acclaimed Forty-Part Motet, which is on long term view in the Gallery’s Rideau Chapel. Drouin-Brisebois describes the techniques Cardiff used to record each singer individually, creating a multipart recording of the 16th-century composition that emphasizes the sculptural quality of the sound.
