The term 'drum kit component' refers to the various pieces of a drum set. The two components mentioned in the crossword solutions are the SNARE and the hi-hat. The SNARE is a cylindrical drum that produces a sharp, staccato sound when struck with a stick or mallet. The hi-hat is a pair of cymbals mounted on a stand and played with a foot pedal. When the pedal is pressed, the cymbals are brought together to produce a closed sound. When the pedal is released, the cymbals move apart to produce an open sound. Both the SNARE and the hi-hat are essential components of a drum kit and are used to create a wide range of sounds.
