Description: Algorithmic composition is the composition of music using formalized methods mostly related to mathematics and programming. This course gives a brief historical background of algorithmic composition from early history to the 21st century, and focusses on current, state-of-the-art techniques, providing a brief outline of their trends in artistic applications. The use of programming for algorithmic composition will be demonstrated, and practical examples will be explored, using the SuperCollider open-source object oriented programming environment. Notions introduced are: Score and instrument, event (note), programming and representing notions from pre-digital music practice (rhythm and tempo, scales and tunings, serialism), randomness and probability, chaos and fractals, markov chains, data based strucures (data sonification), generative grammars, genetic algorithms, neural nets, and sound synthesis techniques (Unit Generators, additive and subtractive synthesis, chaotic generators, spectral modeling, physical modeling, sampling, granular synthesis). Finally, the relationship to other types of algorithmic art forms will be discussed.

*** Participant's Equipment
Participants should bring to class their own laptop computers, (Mac or PC), and their headphones. PC users should use Linux for best results. Obtain Linux MINT XFCE installed on Linux Live USB using the LiLi app.
Evaluation feedback: Present a composition sample or a theoretical paper dealing with algorithmic compositional techniques, and using programming code or giving a historical treatment. In either case, a paper should be submitted describing the work done, in 2500 words or less.
