I believe it was about one year ago that I listened to a song (title is “Hún Jörð” by the band Sigur Rós) on YouTube accompanied by video. I believe the video was taken from a film about Jesus and Christianity. The author used a term for this kind of combination of audio and visual, but I can’t remember it. Could anybody help me out?
Edit: When I looked up the word back then, I believe one of the definitions was something along the lines of “two things moving together” or “two things playing in harmony”.
