Hi-hats provide rhythmic definition and articulation, consisting of two cymbals mounted on a stand. Developed in the early jazz era, hi-hats are now a fundamental part of drum kits. Leading models include Zildjian (K Custom Dark Hi-Hats), Sabian (HHX Groove Hats), Meinl (Byzance Vintage Hi-Hats), and Paiste (Formula 602 Hi-Hats). Closed hi-hats offer tight articulation, while open strokes produce washy sustain, making them versatile for genres from funk to rock.
