As a non-musical production intended for reading, a composer’s personal website can be considered, as a whole, as a composer’s “writing” in addition to serving as an archive for different forms of writing by or about the artist (presentation texts about works, interviews, etc.). Comparative analyses of a certain type of text that is omnipresent on composers’ sites—the biography—as well as the approach to a presentation text about a work provide an insight into the composers’ self-presentation strategies and the way they present their music. These analyses lead to the observation of a general tendency towards the production of contents for music professionals and the under-exploitation of the possibilities offered by digital technology for the promotion and mediation of contemporary music.
