Querbeat is a German brass band and pop ensemble originating from Cologne, known for blending elements of brass band tradition, pop, funk and carnival music. Formed in the late 2000s by a group of young musicians, the band evolved into a large, high-energy ensemble featuring horns, percussion and vocals, and became associated with Cologne's Karneval scene while also performing at festivals and concerts nationwide. Their music combines upbeat brass arrangements, catchy melodies and rhythm-driven grooves, often arranged for live, participatory performance and designed to engage audiences in communal singalongs and dancing.
