The Magical Mystery Chime features a musical phenomenon known as Octave Doubling. Here's how it works: Do you remember the Do-Re-Mi-Fa-So-La-Ti-Do scale from the Sound of Music? The "Do" notes that come at the start and end of this scale are the same note, an octave apart. Notes separated by an octave are considered harmonically equivalent and "ring" together in a way that adds a pleasing sound to the music. This chime takes this theory to the extreme - all the notes of the wind chimes are matched with its "octave double." Never before used in windchimes, this special tuning creates a heightening of the harmonics, creating a song that must be heard to be believed. The Butterfly's Farewell Chime mirrors the strikingly beautiful pentatonic melody at the climactic finale of Puccini's popular opera, Madame Butterfly. When all is lost, the leading soprano uses a full range of human emotion to express her intense passion to restore her honor as the music builds in this tragic love story.
