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

Famous quotes containing the words models and/or composition:
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
“Those Dutchmen had hardly any imagination or fantasy, but their good taste and their scientific knowledge of composition were enormous.”
—Vincent Van Gogh (1853–1890)
