Models For Algorithmic Composition

There is no universal method to sort different compositional algorithms into categories. One way to do this is to look at the way an algorithm takes part in the compositional process. The results of the process can then be divided into 1) music composed by computer and 2) music composed with the aid of computer. Music may be considered composed by computer when the algorithm is able to make choices of its own during the creation process.

Another way to sort compositional algorithms is to examine the results of their compositional processes. Algorithms can either 1) provide notational information (sheet music) for other instruments or 2) provide an independent way of sound synthesis (playing the composition by itself). There are also algorithms creating both notational data and sound synthesis.

However, the most common way to categorise compositional algorithms is by their structure and the way of processing musical data. One of the most detailed divisions consists of six partly overlapping models:

• mathematical models
• knowledge-based systems
• grammars
• evolutionary methods
• systems which learn
• hybrid systems
