This wind chime plays the famous tones of London's Big Ben, pealing out glorious sounds of celebration and spiritual richness. The unique sound of these long tubes is the result of a phenomenon called the missing fundamental, a special way our brain perceives the vibrations from our ear. This occurs when a sound's overtones suggest a frequency to our ear that the sound itself lacks. Our Chimes of Westminster play the same traditional and joyous melody as the Westminster Quarters heard in the streets of central London for over 150 years.
