Demicadens, also known as Musicalfluid or Musicalflux is an audiogender in which one only experiences gender when listening to music. One's gender mirrors whatever music they are listening to. When one listens to music, their gender changes- it could be a musciagender, which is specific to the song or genre one is listening to, but it does not necessarily have to be, one could experience any gender when listening to music. When not listening to music one is agender.
Demicadens coined by Tumblr user Sonic-Mogai-Blog (now deactivated) on May 8th, 2019 after an anonymous asker described the gender.
