The 4th International Workshop on Computational Music Theory, to be held at ESMUC in Barcelona July 16-20th, will concentrate on collaborative problem-solving on musical similarity with special attention to Flamenco music. Actually, the title of this year's workshop is Computational Models for Music Similarity applied to Flamenco Music. One of the goals of the workshop is to start new collaborations on research topics involving the interplay of mathematics and music. The structure of the workshop will consist of background lectures, brain-storming sessions, and playing music together. Some reading material will be given to the participants before the workshop in due time. The workshop activities will then be divided into two large areas: the study of current state of the art research, and the discussion of current research problems.

This workshop is organized in collaboration with the ESMUC and the Music Technology Group of the Pompeu Fabra University
