Music on Computers
To start, I want to go back to the late 70's, when computers became available for home use, when Hal Chamberlin wrote:
"Computer music is probably one of the most talked about serious applications for home computers. By serious I mean an application that has a degree of complexity and open-endedness which can totally preoccupy experimenters and funded institutions for years. Computer performance of music is a discipline so vast that the final, 'best' technique for its implementation or even a good definition of such a technique may never be discovered."
A Sampling of techniques for computer performance of music - Hal Chamberlin (Byte, September 1977)
Given that about 38 years later we are still here, we can state that the discipline is indeed quite vast.
