Tyler over at Oddstrument Collection did a wonderful interview with sculptor Bruce Gray. I really love this piece of his, it’s all jangly and clashy.
BG: I think that any sculpture that is designed to produce at least one musical tone can be considered a musical sculpture. Many of my sculptures could also have multiple classifications like a rolling ball musical kinetic sculpture, for example. I would include all my rolling ball machines as musical sculptures, even if they have just a few chimes on them. The rolling ball machines have lots of other great sounds too. Even just the sound of the steel ball running along the track is kind of mesmerizing. I love to include lots of musical stairways that resemble xylophones in most of them now.
