Chord Time: planetary motion as harmonic timestamps
The Granular Atom of CosmoHarmonics
Every moment in time has a unique harmonic signature.
Chord Time is the fundamental unit of CosmoHarmonics. At any given instant, the planets in our solar system occupy specific positions in their orbits, each moving at a unique velocity determined by Kepler's laws of planetary motion.
We translate these orbital velocities into musical frequencies. Mercury, racing around the Sun, produces higher pitches. Mars, in its slower outer orbit, contributes deeper tones. Together, the inner planets form a four-note chord that exists only at this precise moment in cosmic time.
“The chord you just heard has never existed before in human history, and will never exist again in exactly the same way. It is the solar system's motion at this instant, rendered as sound.”
This is the granular atom: the smallest meaningful unit of cosmic music. From here, everything else emerges: chord progressions across days, harmonic patterns across seasons, symphonies spanning decades.
From Atoms to Compositions
Just as you might use pandas to analyze time-series data, you can sample cosmic chords at any interval (hourly, daily, yearly) to discover harmonic patterns hidden in celestial mechanics.
Daily sampling: reveals melodic contours as planets shift positions
Monthly intervals: create chord progressions with orbital cadence
Yearly snapshots: compose long-form harmonic structures
The cosmos is always playing. Chord Time lets you listen.

Real-time cosmic chords
We continue this tradition by using NASA JPL ephemeris data to derive actual musical frequencies from planetary velocities, available in real-time on the web, with an API in development.
Instead of asking
“What time is it?”
We ask
“What chord is it?”
How It Works
01
Planetary Velocity → Frequency
Each planet's orbital velocity (from NASA JPL data) maps to a musical frequency. Mercury moves fastest → highest pitch. Mars moves slowest → lowest pitch.
02
Four Planets → Four-Note Chord
Mercury, Venus, Earth, and Mars together form a four-voice chord at any given moment. This chord changes continuously as the planets orbit.
03
Harmonic Timestamps
Any date and time has a unique cosmic chord. Sample these chords across time to create progressions. Use them in composition and improvisation.
