A project that explores whether there is a musical equivalent to the curvature of spacetime will be presented on Thursday 6 July by Gavin Starks at the National Astronomy Meeting at the University of Hull.

Starks, who has a background in radio astronomy and , has been working on developing an 'acoustic cosmology' for more than 20 years in collaboration with Prof Andy Newsam of Liverpool John Moores University. Their aim is to test whether mathematical relationships that describe cosmology and quantum mechanics can be applied to a sonic , or 'soniverse'.

Starks explains: "If we look at the way that has evolved from mediaeval plainsong to the algorithms that generate current chart-hits, we can see parallels developing in the way we describe music and descriptions of our perception of the universe. We can now create new types of sound from scratch – electronic sounds that simply couldn't have existed before. It leads us to think about a digital sound world that we can't enter, because it physically doesn't exist. The question is – what next?

"We are starting to develop completely new ways of manipulating the microstructure of sound, as well as the macroenvironment in which we experience it. This raises questions about whether we can create a soniverse based on a set of fundamental equations, in the same way that we can create mathematical models of the universe."

Starting with a single wavelength 'sonon', a fundamental particle in the soniverse equivalent to a photon, Starks has attempted to define its properties and the physics that may apply to it. The project's initial model of 'wave-time' has three independent dimensions: the individual sonon wavelength, instrument time (the duration that an individual instrument plays) and performance time (duration equal to the length of an individual piece).

Some of the relationships explored to date are causal (i.e. the physics is consistent within the soniverse) and some are aesthetic (i.e. they describe a subjective musical construct). Many have direct parallels in the physical universe. For example, the listener in the soniverse is analogous to the observer in : a sonon is only rendered musical or not when it is heard. A temporal gravity allows the clustering of sonons to create rhythms or musical phrases. Wave-time can be bent by clusters of sonons, in the same way that gravity distorts space-time in the universe.

Starks believes that bringing together cutting-edge science and understanding of musical structure creates the opportunity for discovery: "There's a long common history between physics and music, for instance people built columns in cathedrals at a height linked to the resonant frequency, even before they understood the nature of pressure dynamics. It's a relatively recent phenomenon that art and science are treated as different disciplines. By bringing them back together, and creating a common language, we can find different ways of interpreting and thinking about both music and cosmology."

Newsam adds: "As astronomers, our experience of the universe is essentially visual - images, graphs, and so on. With the soniverse, we hope to create a new way to appreciate the cosmos, using our instinctive grasp of music and tone to explore relationships between different objects and cosmological models."

Contrary to this line of thinking, classical music has already achieved a harmony, if you will, between music and science. But the link is the biophysics of the human singing voice and well tempered tuning. The registers of the voice are the basis for the musical scales and keys for classical composition. The epitome of this relationship appears in the works of J.S. Bach. Musical instrumentation extends and enhances this lawful interrelationship. This was furthered by the compositions of Mozart, Beethoven and Brahms and their epigones.

In the mid to late nineteenth and twentieth centuries arbitrary melodic chromaticism and defiance of this lawfulness began to hold sway with such anti-well tempored inventions as the twelve tone row. However, this does not negate the true science of well tempering.

Huh? Is this a new kind of frequency analysis or more BS?

In what sense does an orchestra parallele the masses, geologies, plasmas, liquids and ethers, orbits and reactions present in the universe? not that much. metaphysical not science.

the sound generated within the universe (chaos/mass based) is very different to music. Music uses psychologically relevant patterns, it is sonic art. the application of maths and physics to "music" which is composed, generally fails, and the only corrective factor is using human interpreted rythm and melody consonsance dissonance and all that. Nothing in the universe uses
12 tone selectively matched wavelengths to create a highly ordered chord system with octaves. general midi tuning is indeed well tempered as gumbob seems to imply. they are not reconciling very fertile fields together: SIMPLICITY IS KEY when matching useful sciences, similar to biomimickery.

It would be cool to search for a relationship between birdsong and cosmology. they contain highly unrelated math patterns. it's same as attempting to make mathematical formulas to generate life and lifelike plants. it's something that only AI can do, because the algorythms take verrrrrrrry many exceptions and nuances, it's not in the realm of common human ability. and they seem to want to do the inverse, use biologically inspired sound to analyse the universe? omg
