This Bells of Paradise 32 in. Medium Chime - Pacific Blue features an elegant blue that is pleasing to the eye and uses an ancient acoustic system known as just intonation to assure its sounds will be pleasing to the ear. Tones produced through just intonation use whole-number ratios that relate the frequencies at which the separate six tubes featured in the chime vibrate. Sounds confusing but rest assured it will also sound beautiful! The chime also includes a silver aluminum top and windcatcher.
