This article examines the forms and levels of social media investment among composers of contemporary music. The speeches of the six young composers presented and analyzed here open a small window on the ways in which the entrepreneurial spirit influences their professional practices. Sensitized by peers as well as by certain school experiences to the objective need (because imposed by the conditions of compositional work) to “communicate” and to manage their own image as an artist, they invest in a variety of social media by arranging for their specific characteristics—personal websites, SoundCloud, YouTube or Facebook accounts, personal blogs, etc.—in order to gain visibility. While their uses and dosages of online writing may vary in function of aesthetic considerations as well as their artistic ages, they reveal some tensions generated by injunctions to self-employment, since the logic of symbolic profit opposes disinterestedness linked to the figure of the romantic artist.
