Eleven bodies, eleven frequencies.
The slower the body, the lower its tone: Pluto at 8 Hz, Mercury at 131 Hz, everything else between. Most sit below the practical floor of hearing, so each is octave-folded into the audible band — which moves the register and preserves every ratio between them.
| Body | Base | Folded |
|---|---|---|
| Sun | 30.0 Hz | 120.0 Hz audible |
| Moon | 80.0 Hz | 160.0 Hz audible |
| Mercury | 131.0 Hz | 131.0 Hz audible |
| Venus | 51.4 Hz | 205.6 Hz audible |
| Earth | 31.7 Hz | 126.8 Hz audible |
| Mars | 47.0 Hz | 188.0 Hz audible |
| Jupiter | 26.7 Hz | 213.6 Hz audible |
| Saturn | 34.0 Hz | 136.0 Hz audible |
| Uranus | 19.0 Hz | 152.0 Hz audible |
| Neptune | 12.0 Hz | 192.0 Hz audible |
| Pluto | 8.0 Hz | 128.0 Hz audible |
The order is not arbitrary and it is not alphabetical: the slower the body, the lower its tone. Pluto sits at the bottom and Mercury at the top, which is the same ordering the sky has.
A single body is only half the instrument. The Solar HARP is built on pairs — two bodies and the angle between them — so the frequencies here are the raw material rather than the output. The aspect sounds are what happens when the angle applies its ratio.
Frequencies are the instrument's own and are checkable by pressing play. Horoscorpio makes no therapeutic claim.
