* Episodes of SaladFingers use the odd little tune "Beware the Friendly Stranger" by BoardsOfCanada at least once per episode. In one episode, it is played backwards, [[MindScrew for no other reason besides the fact that they could]].
* ''{{WebAnimation/RWBY}}'':
** Background music that plays while the focus is on Blake tends to be played with piano.
** Roman Torchwick has a sinister violin and piano piece that plays when he appears.
* In ''WebVideo/IfTheEmperorHadATextToSpeechDevice'', "Awake" from ''Anime/JoJosBizarreAdventure'' plays whenever the Fabulous Custodians are on screen. The Ultramarines also have their music, heavy with chanting and classical tones.
* Whenever things get deep around Dictator Pickles in WebAnimation/AlfredsPlayhouse, II. Allegretto by Zagreb Philharmonic Orchestra can be heard growing in the background. Labby also has a dark organ tune follow him in TheMovie.
