The MEINL Planetary Tuned Gongs
"The MEINL planetary tuned Gongs are made in Germany in the European gong-making tradition. Using the calculations of Hans Cousto (The Cosmic Octave) to match the frequencies of the sun, moon, and planets, each gong is tuned to produce the corresponding frequency. These gongs are handcrafted by the gong makers to respond with great sensitivity in all playing applications. Their mysterious sound comes from the countless hours spent hand-working the metal. It is atmospheric and soothing. They are available in 24”/61cm up to 36”/91cm in diameter."
