The Meinl Sonic Energy Cosmic Bamboo Chimes produce soft, resonant tones that fill your space with calming sounds. Use the chimes for meditation, sound baths, and yoga, or simply relax at home. To play, hold the string and gently swing the chime in a circle or from side to side. Inside, there is a pendulum and several metal rods tuned to specific pitches. You can vary the sound by switching between the two included pendulums: acrylic (hard) and wood (soft). Guide the end of the pendulum with the attachment hook through the bottom of the chime. Hang it on the wooden bridge. Finally, pull the string straight, turn the chime upside down, and you can start playing. Available in four tunings adapted to different times of the day: Aurora (Morning), Sol (Day), Luna (Evening), and Stella (Night). Combine two or more Cosmic Bamboo Chimes to vary the mood. The package also includes a sturdy carrying bag and two replacement pendulums (acrylic, wood) per chime.
