Our Magical Mystery Chimes, our Encore Chimes of the Eclipse, and our Encore Chimes of Orion feature a musical phenomenon known as "Octave Doubling".
Here's how it works - you remember the Do-Re-Mi-Fa-So-La-Ti-Do scale from the Sound of Music? The "Do" note that comes 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.
Our octave doubled chimes take this theory to the extreme - all the notes of the chime are matched with the same note, an octave apart. Never before used in windchimes, this special tuning creates a heightening of the harmonics, creating a song that must be heard to be believed.
