From Nano-Wiki :: Music of the Nano-Spheres by Roger Malina, April 15, 2010:

There is a several thousand year history of associating music with cosmic phenomena, the famous “Music of the Spheres” created from the regularities in the astronomical universe. Even though of course there is generally no sound in outer space, because the conditions of pressure and density to allow acoustic waves are very rare.

The same urge motivates artists and scientists interested in sonifying

Sound Artist Peter Gena has a large collection of DNA Music and other sonifications of molecular structures: http://www.petergena.com/DNAmus.html

Like Kepler, and many others who subscribed to the Pythagorian ideas, Gena believes that:

“… a musical reading of DNA ought to be rendered literally. As the sequences represent life of many sorts, I am reluctant to tamper with the “score.” The DNA mixer can realize sequences as digital sound and/or print them out in musical notation. Ideally, performances of the gene sequences should be executed live from the computer as in an installation, where the ribosome simulations can be positioned spontaneously before playing. Red Blood Cells is a mix of five genes that are present in human blood: alpha and beta globin, heme synthetase, transaldolase, and glucose 6 phosphate. These are realized simultaneously, just as they are produced in the body. “
