Janet Cardiff's sound installation 40 Part Motet is at Brighton's Fabrica Gallery until the end of May. I have started to go every time I'm in town; after a singing workshop, on my lunch break. There's something very moving at a gut level in hearing 40 beautiful human voices in a piece of such purity and wonder. There are 40 speakers arranged around the space, each carrying a separate voice. You can stand in the middle or walk around or stand close to one voice, or two. Between 'performances' Cardiff has recorded the background chat of the performers. My favourite is two choir boys talking about their watches.
I'm not a religious person but when I hear sounds like these I'm both humbled and proud to be a human being, to belong to a species capable of creating work of profound joy and wonder.
