Abstract

Although Algorithmic composition became popular with the rise of computers, algorithmic thinking is far older - it can be traced back to the ancient times of Pythagoras and the Jewish Kabbalah. It is a method of perceiving an abstract model behind the sensual surface, or in turn, of the construction of such a model in order to create aesthetic works. Behind the various approaches there is one common denominator: a longing to create something infinite that exceeds the limited horizon of our individual knowledge. Seen in this light, algorithmic thinking and its application in the arts can become a way to gain experience and to overcome barriers that are either implicit in ourselves, or erected by our social environment.

In this article, I am focussing exclusively on the use of algorithms in the compositional process. My primary aim is to demonstrate how the algorithmic spirit has evolved through the centuries - from medieval music theory to the interactive realtime generated computer music of today.

Notes

Karlheinz Essl’s examination of algorithmic composition is similarly wide-ranging, though it stays mainly within the “art” end of the sphere, examining rule-based and semi-automatic compositional systems from the Musica enchiriadis, via multiple serialism (and related trends and developments in the work of Xenakis, Koenig, and Cage) to Brian Eno’s Music for Airports and the implementation of real-time algorithmic tools with Max/MSP. His suggestion that some of these real-time tools might be capable of subverting the common perception that algorithmic composition removes some of the “artistic” freedom from compositional work is particularly pertinent to the debate and is also an opinion that would have been more difficult to make without some of the most recent examples cited by Essl, such as González-Arroyo and Eckel’s Raumfaltung (2003).

Karlheinz Essl's "Algorithmic Composition" presents a useful overview of the field linking pre- computer process musics that involved style rules, serialism, and chance operations to ongoing real-time experimentation.
