Music 254/CS 275b Spring 2014 Syllabus

Music 254/CS 275b "Music Query, Analysis, and Style Simulation"
Stanford University (Spring 2014).

This music information retrieval course builds on the foundation of Music 253/CS 275A. Using an open-source analysis platform (such as the Humdrum Toolkit (unix), Humdrum Extras (C++), or Music21 (Python), or your preferred programming language/environment) students plan and design their own applications.

The first four weeks cover basic areas of music analysis and retrieval and introduce basic principles of using the Humdrum Toolkit. Students may be assigned individual reading assignments pertinent to their research topic areas. The remaining six weeks are spent on individual project development, with weekly reports and discussions. Extensive help is available in the lab during hours allotted to class time. Students give verbal and written reports on their research at the end of the quarter. Some projects may be appropriate for continuation in independent-study modules.
