Following on from the teaching of Florence Badol-Bertrand, this course offers an exploration of the tools used to write about music, edit scores, initiate dramaturgical reflection or carry out mediation activities (reviews, communication, critical apparatus, programme notes, etc.). Like a workshop, many of the projects are carried out in a real or simulated professional environment, which creates the conditions for discovering and appropriating research and mediation approaches. They also include an introduction to the sociology of classical music audiences, cultural institutions and public cultural policies.
