Concert percussion is the beating heart of a large ensemble, providing the swells, accents, and booms that give foundation to an orchestral performance. Comprising a wide range of instruments from the mallet percussion entries of xylophone and tubular bell to auxiliary examples like snare and symphonic cymbals, perhaps the best-known example is the iconic timpani or "kettle drum", famed for it brazen, rumbling presence. While not as flashy as the first line of violins or the glint of the brass section, concert percussion is a cornerstone of orchestral and symphonic experience.
