The Meinl Sonic Energy Cosmic Bamboo Chimes produce soft resonant tones that fill your space with serene sound. Use for meditation, sound baths, and yoga. Or create a relaxing space at home for reflection. Hold the cord and gently swing the chime to activate its sound. Inside is a pendulum and a group of metal tines tuned to specific pitches. Easily modify the tone by switching between the two pendulums: acrylic (hard) and wood (soft). Insert the clasp end of the pendulum through the bottom of the chimes. Attach the clasp to the hook on the wood crossbar. Pull the braided cord straight and pick it up to play the chimes. This set contains four tunings matched to the time of day: Aurora (morning), Sol (day), Luna (evening), and Stella (night). Also included is a sturdy carrying case and two spare pendulums (Acrylic, Wood) per chime.
