Clarinet accessories comprise reeds, mouthpieces, and clips. Reeds vary in size and hardness, affecting timbre from soft to bright. Harder reeds produce a firmer sound; the French cut offers a delicate tone, while the American cut is thicker and bolder. Mouthpieces, made of bakelite, rubber, crystal, or metal, influence tone through their inner shape and opening size. Clips, available in metal and plastic with different screw designs, secure reeds for stability. Their material and design impact reed pressure and vibration, allowing performers to adjust tones according to repertoire and performance conditions.
