OpenMusic is a graphical programming environment intended to assist the composer.
This program introduces participants to the graphical interface environment as a composer: discovery and use of the OpenMusic interface, creation of patches with the use of musical editors and algorithmic generation of musical sequences, an introduction to musical formalism, and the use of two types of models used in 20th century music, stochastic or random models used in "spectral" music.
Upon completion of this course, participants will be able to use the main functions of OpenMusic (create and open a workspace, load a library), to create simple patches, to represent and preform musical sequences with tools available in OpenMusic (chord, chord-seq, voice, multi seq, poly, and maquette), to import and generate MIDI files, and formalize simple musical problems. Participants will have acquired the conceptual and technical foundation necessary in computer-assisted composition for use in musical writing.
Composers, musicians, teachers and any person interested in computer-assisted composition.
Knowledge of music theory, participants must be able to notes and rhythms;
Basic knowledge of mathematics: arithmetic, geometry (triangles, Pythagorean and Thales theories, symmetry, airs), understanding of powers, equations with a variable, statistics, etc;
Mastery of Macintosh computers (OS X).
Educational Resources and Techniques
Classroom equipped with computers with all the necessary software installed, headphones, and MIDI keyboards;
Class Format: training alternates between presentations, explanations on theory, studying examples to analyze, and hands-on exercises;
Didactic Materials: video-projected presentations and documents.
Supervision and Assessment
Welcome the first day of training beginning at 9:45am;
Attendance controlled; signature of an attendance sheet required every morning and afternoon;
Assessment of acquired knowledge using a multiple-choice test (30 minutes) taken at the end of training.
A certificate at the end of the program is given to each participant with the results of the exam.
Training Period and Organization
24 hours of training. Wednesday- Saturday, December 8-11, 2021. 10am-1pm/2:30pm-5:30pm
11 students maximum
This training program will be held at IRCAM on-site in accordance with local sanitary guidelines and measures in place at the current time. These guidelines and measures may change. In the event that IRCAM cannot physically welcome students, an adapted program will be held virtually. For further information, please contact: info-pedagogie[at]ircam.fr.
