This short composition workshop will focus on the relationship between the subject of a piece and its possible materials. We will explore an approach in which the horizon of a work becomes in itself a source for these materials.  By taking a banal starting point (a pen, a pair of socks, anything) as a subject, articulating its relational fields (interactive, physical, political, sensual...) and reducing these to their essential elements, we will attempt to create original compositions, taking inspiration from musical strategies.
