The completed tool accepts input of periodic systems (ie. lengths of time which repeat) such as planetary orbits and then generates octave values so that the original object can be brought into the human audible spectrum.

To clarify, you give the computer a length such as 570.84 days and the computer gives you:

1. The nearest western chromatic pitch-class, eg. G#
2. The range of exact frequencies within the audible spectrum, eg. 78.341hz
3. The range of musically useful durations (defaulting to between 1/10th of a second and 30 seconds)
4. The equivalent frequency of light in terahertz and the name of the colour-band into which this places the light

So in other words you could start off with the orbital period of the Earth round the sun, and the database would tell you that this is broadly a C#, is equivalent to a particular colour of green, etc. and there is the option to generate a detailed printable report.

Please bear in mind that I am not saying that the Earth IS green, nor that Mars IS blue : simply that the orbit of those planets around the sun is octave-equivalent to those frequencies of light.
