The Aeolus Acoustic Wind Pavilion is a wind-singing metal sculpture by Bristol-based artist Luke Jerram that lets windy gusts and breezes find their capacity for articulation. Using no electrical power to assist the melody-making, nylon harp strings are attached to some of its tubes, diverting wind into the centre of the work to create sound. Even the unstrung tubes are tuned to an aeolian scale to hum at low frequencies.
