Le politique investit aussi les champs médiatiques des cultures populaires comme le démontre Martin Knust dans son article « Fictionalizing Populism : a music analysis of recent political journalistsoundtracks » dans lequel il s’intéresse aux fonds sonores et à leur rôle dans les émissions dejournalisme politique audiovisuel. Ainsi il explique combien ces musiques d’ambiance ont pour butd’influer sur l’opinion publique et s’apparentent ainsi à de la propagande.

Background music in political journalism has a long history. It is as old as audio and audiovisualmass media, that means, about a century. Surprisingly, media and journalism research have virtuallyignored this communicative layer in journalism and focused entirely on texts and images. This means,that there are no theories or methods for investigating this kind of mass media music that is heard bymillions every day and thus part of a popular culture. This essay is the first attempt from a musicologicalperspective to get a grip on non-diegetic music in political journalism. It will present the problematicnature of this music that shares features with fictional film music on a surface level. But since it accompaniesstories, images and statements that are non-fictional, its function and ontology have to be seenas fundamentally different from feature film music; it is linked to political opinion shaping and the articulationof political programs and does in fact share features with political propaganda on a deeperlevel.
