A bridge between scales

One cycle. Many octaves.

In Hans Cousto’s cosmic octave approach, a repeating astronomical cycle becomes a frequency. Repeated doubling carries that very slow rhythm into the audible range.

For the tropical year, about 31.56 million seconds, 32 doublings give approximately 136.10 Hz. Move down one octave to hear 68.05 Hz, or add a lower foundation at half and quarter of your chosen tone.

Listening notes

Explore the relationships.

Begin with Earth’s year. Add a little warm hum and bass, then slowly introduce the Moon or Venus. With two close tones, listen for the rising and falling interference pattern. The interval readout follows your actual tuning.

The pulse is gentle amplitude modulation. Its tempo starts from the reference tone divided into a slower rhythmic octave; pulse spacing lets that movement unfold over one, two, four, or eight beats.

These are synthesized musical mappings of cycles. Planetary colors are approximate screen interpretations of the chart. The orbit artwork is symbolic, and the Sun preset follows Cousto’s theoretical solar reference. The instrument does not reproduce recordings from space or establish a biological effect.

Start with quiet device volume. Stop if listening becomes uncomfortable. Saved mixes remain in this browser; audio starts only after you press Begin.
