The sounds produced by these methods are ordered representations of the solar system. They complement existing visual and numeric representations, opening a new astronomical way of perceiving our cosmic neighbourhood. At first blush, the products may sound like random noise, but the underlying order that provides their structure means they provide an ambient model of the time from which the notes were derived. The opening post gave an example from July 2008. This could be played in about three minutes at a rate of one note per second. The use of midi electronic music technology means the data for any time period for which planetary positions is known can readily be entered, giving a sonic representation drawn from a function of the empirical data. For example a year of planetary data could be represented in two minutes of music. Experimenting with different options by varying speed, rhythm and tone will result in a range of creative options for musical depictions of the harmony of the spheres.
