Clutterfunk is a composition by Norwegian electronic musician Waterflame and is used as the soundtrack for the eleventh official level in Geometry Dash. The level helped make the track familiar to rhythm-game players through its fast movement, changing sections, and demanding obstacle patterns. Melodica versions reinterpret its electronic lead with a small keyboard wind instrument, giving the tune a lighter, comic character. Short excerpts continue to appear in gaming edits because fans can recognize the melody almost immediately, even when it is reduced to a single compact note.
