These chimes have an extra rich sound!
This feature gives you two chimes in one. Chimes that feature Octave Doubling have each note (tube) repeated one octave higher. Notes separated by an octave are considered harmonically equivalent and "ring" together in a way that adds a pleasing sound to the music. Never before used in windchimes, this special tuning heightens the harmonics, creating a song that must be heard to be believed.
