Electronica is a broad genre of electronic music that encompasses a wide range of styles. At its core, electronica is characterized by the use of electronic instruments, including synthesizers, drum machines, and samplers, to create complex and intricate soundscapes. One notable subgenre of electronica is industrial music, which emerged in the late 1970s and early 1980s and is known for its aggressive, metallic sound and its incorporation of unconventional instruments and found objects. Electronica music is often used in films to create mood and atmosphere, and can be found in everything from action movies to documentaries.
