Each pyramid is handmade. They vary slightly. This size pyramid measures 12"x12"x9.75" tall and is welded together from 14mm rods. Paired with a small Bamboo Magic Mallet for rub or striking. We do not guarantee any specific note for this product. Smaller pyramids will have higher tones while the larger pyramids have a lower fundamental tone. What sets the pyramid apart from other quartz instruments is the built in interference achieved by having all of the quartz rods ringing out at one time.
