In 1978, in a team of scientists and artists, the Swiss mathematician Hans Cousto had the ingenious idea of using the resonance law of the octave to transpose planetary cycles into the audible range. Fritz Dobretzberger, a member of the team, initiated the first production of planetary tuning forks and 12 years later founded the Planetware Infopool to inform about the cosmic octave together with Cousto.
