Drumsticks are typically made from wood, nylon, or carbon fiber, and have various head shapes like round, oval, or triangular. They measure 38-42 cm in length and differ in thickness, catering to various musical styles and performance needs. Weight and balance are crucial; wooden sticks weigh 40-60 grams, while carbon fiber is lighter and nylon falls in between. Well-balanced sticks enhance control over strength and rhythm. Drum brushes consist of a brush head (metal or plastic) and a wooden or plastic handle. Key features include wire length and thickness, with longer wires producing softer tones and more wires resulting in fuller sounds. Common handle lengths are 25-35 cm, with diameters between 0.8-1.5 cm.
