This chime is tuned to the opening phrase of Clair de Lune, a distinctive melody made up of seven two-note chords. To replicate this, the chime was designed with two different sized clappers, so both the upper and lower tubes are struck at the same time. In this way, it plays double stops, or two notes at one time. Clair de Lune translates to Light of the Moon or Moonlight and is the third movement of the Suite bergamasque, one of the most famous piano suites composed by Claude Debussy. First written around 1890, when Debussy was only 28, this melody was used for the Bellagio Fountain scene at the end of Oceans Eleven. A true original, there's no other windchime designed to play chords in this way.
