Woodstock Percussion Wind Chimes are tuned using a computerized tuning process in order to achieve incomparably beautiful sound. These wind chimes also use an ancient tuning system known as just intonation. Because these notes fall between the notes of a piano (which is tuned using the modern equal temperament system), the chime has a unique, authentic quality. The frequencies at which the different tubes vibrate are integrally related, thus producing the purest musical intervals. Once you hear the beautiful tones created by these magical chimes, you will understand why they are so popular around the world.
