Lähdemusiikkiin

Lähdemusiikkiin is a Finnish term that translates to "source music" in English. It refers to diegetic music within a film, television show, or other narrative medium. Diegetic music is music that originates from within the story world and is heard by the characters as well as the audience. This contrasts with non-diegetic music, also known as score, which is added for emotional effect and is not perceived by the characters.

Examples of lähdemusiikkiin include a song playing on a radio within a scene, a character singing or playing an instrument, or music emanating from a nightclub or concert that the characters are present at. The source of the sound is clearly established within the narrative. The use of lähdemusiikkiin can enhance realism, provide character development by revealing their musical tastes or skills, or contribute to the atmosphere and mood of a particular scene. It grounds the audience in the reality of the fictional world by presenting sounds that would logically exist within that environment. The distinction between lähdemusiikkiin and score is a fundamental concept in film sound design.
