Why Beatrix Farrand built an amphitheater at Dumbarton Oaks is still a mystery. The seating replicates a Roman amphitheater on the Gianicolo in Rome: it’s stage is a pool. What is audience intended to look at? This is a part of the garden, visitors often neglect to visit. The Pool of Bamboo Counterpoint by Hugh Livingston opened on the first day of the The Sound and Scent in the Garden Symposium at Dumbarton Oaks. The sculpture features 12 “organ” pipes rising out of the water. The sound emanating from each pipe is controlled by a hidden computer. The sounds are a “shuffle” of many variations: piano riffs, various percussive notes, wind instruments and some sounds recorded in the garden and remixed by Livingston. Dumbarton Oaks continues to surprise.
