A hi hat
The hi-hat, in Spanish, the charles, is one of the base parts of the battery, consisting of two cymbals of the same size that can be played with a pedal. Functioning
The hi-hat consists of two cymbals, mounted on a tripod. A pedal at the base of the latter drives a mechanism that makes them collide. A thin screw passes, through a hollow tube, both cymbals, connecting with a pedal. The upper pan is connected to the screw by means of a spring, while the lower pan remains fixed, resting on the hollow tube. The heights of the upper plate and the lower plate are adjustable, which allows changing the height and the degree of opening.
There is also another type of hi-hat that works by pressure. The tube is removed to give way to a flexible cable filled with air, which allows to place the pedal and hi-hat in different places. Normally the hi-hat is coupled to a rack. This is very useful for drummers who use several charles, since it allows one to put one in the right hand, and being almost all the right international batteries, comes very well not to cross constantly.
When the pedal is pressed, the upper plate hits the lower one, (closed hi-hat). When released, the upper pan returns to its original position on the lower pan (open hi-hat). A tension unit controls the amount of pressure required to lower the upper plate, as well as the speed with which it returns to its open position. In this way two types of blow are created with the foot of hi hat: the blow open and the blow closed. The open blow consists of making both plates collide and automatically leaving them in their initial position, so that the cymbals continue to vibrate and the sound is long. The closed blow or 'chick' that is is just close the charles.
The hi-hat cymbals are usually two 14-inch plates, the bottom one being heavier than the top one to support the hi hat effect.
Some drummers use the loose hi hat to a certain height, such as to use the double bass drum or double pedal.
The Sabian platter brand launched a triple hi-hat, designed by Peter Kuppers. The triple hi-hat is that when the pedal is pressed, the bottom plate goes up, and the top plate goes down, hitting both the plate in the middle.
