Two hundred and fifty reed-like forms from 12-14 feet in height are made of stainless steel and resin. Translucent resin heads hold compact transducers. The array produces a light, airy sound field derived from indigenous birdsong, with an underlying melodic structure. Tone Reeds self-illuminate through perforated steel sleeves and cores and translucent resin stalks and heads, with subtle lighting effects that move in response to the presence of people.
