The invention provides a sound reduction enclosure for hi-hat cymbal assemblies, enclosure which can be fastened directly to the hi-hat stand to greatly reduce sound leakage and offer more precise control of sound emissions during recording sessions and live performances. The enclosure is made up of two (2) primary elements: 1—the main, funnel-shaped body that attaches to the hi-hat stand and surrounds the cymbal assembly, containing and allowing control of the sound; 2—the different lids that provide yet greater sound reduction and control. With or without its lid, the invention allows the user to both: 1—activate the hi-hat cymbals using the pedal; 2—strike the hi-hat cymbals using the drumsticks.
