Product Information
The Meinl Sonic Energy Platonic Year Gong is a 28" handcrafted resonant instrument tuned to the Platonic Year frequency derived from Hans Cousto's "The Cosmic Octave." Forged and hand–hammered in Germany from nickel silver, this gong produces deep, sustained tones at 172.06 Hz (F2) when calibrated to A4 at 433.56 Hz. Each instrument is unique, with natural variations in surface hammering and colour from the high–temperature forging process.
The gong's precise tonal calibration arrives through meticulous hand–hammering during manufacture, ensuring frequency accuracy for sound healing and meditation applications. Its 70 cm diameter generates rich, resonant frequencies that sustain and evolve, creating immersive soundscapes. The nickel silver alloy provides tonal clarity and projection, while the handcrafted surface–work contributes to the complex harmonic content. Includes protective cover and handling gloves for maintenance and transport.
Sound therapists, meditation facilitators, and musicians working with frequency–based composition will find the Platonic Year tuning valuable for creating calming, atmospheric sessions. The gong's connection to cosmic octave mathematics offers a foundation for exploring tuning systems beyond standard concert pitch, enabling deeper exploration of acoustic healing and vibrational work.
