The Prime Oscillation

Play two tones at once on an organ pedal board. If they are five notes apart - the do-re-mi-fa-sol interval - you will produce a tone that is an octave lower than the lowest note you played. This is a church organist's trick used to get 32 foot sound from 16 foot pipes. Tones in the lower octaves of a piano can produce the same effect. Play C and G and you will hear another C an octave lower. It will wobble a little because of the tempered scale.

When the lower C itself is played, tones sound within it, overtones. These include the C an octave up and the G a fifth beyond that, sounding at their fundamental pitches - true pitch, not tempered. They are overtones of the lower C. When they are played, they reconstitute the lower tone. Any pair of tones will tend to construct a lower tone. Any pair of tones can be in an overtone series.

Oscillating masses in the universe - rotating planets revolving around their star, galactic aggregates - all connect gravitationally. Each influences the others' paths.

Not all planets are playing in the key of C, but they may be overtones of an overtone that does.

Suppose C and G construct CC, the tone an octave below C. Suppose G and the D five notes above it construct GG. Then CC and GG construct CCC. C and G and the D beyond it construct CCC.

Is there a lowest tone? Can there be there a slowest oscillation in the universe?

The universe is infinite. Can the pitch then be infinitely low, the motion of the oscillation infinitely slow?

What is infinitely slow?
