leitmotif [(leyet-moh-teef)] A frequently recurring bit of melody, usually in opera, associated with a person, thing, or emotion; Leitmotiv is German for âleading theme.â The leitmotif may be heard in the instrumental or the vocal part. Note: Leitmotifs are particularly associated with the operas of Richard Wagner.
Synthwave (2000s genre) Synthwave (also called outrun, retrowave, and futuresynth) is a genre of electronic music influenced by 1980s film soundtracks and video game music. Beginning in the mid 2000s, the genre developed from various niche communities on the Internet, reaching wider popularity in the early 2010s.
Darkwave is arguably not a top-level electronic genre (in the same way that techno, trance and house are), I think it should be a subgenre of industrial music and gothic rock, or some combination. Compare industrial music vs darkwave techno music vs darkwave, and house music vs darkwave.
