This chime is tuned to the distinctive opening phrase of Clair de Lune, a 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. This chime was designed with a removable wind catcher for easy customization. Including a personal message such as a wedding date, note of sympathy or birthday greeting makes the gift that much more special. Woodstock Chimes does not offer engraving services, but the removable wind catcher can be taken to a personalization store, trophy shop, printer or jeweler to be engraved or silk-screened.
