If you have ever played the drums, you know that every little thing makes a big difference in sound. Stretching or loosening the skin even just a little on any side changes the tone of the drum. Cymbals cannot be tuned, though; if you want a different sound from a cymbal, you need to buy a different one. And one of the best is zildjian.
Zildjian has been around for almost as long as they have been manufacturing trapkits and are well known throughout the industry as being among the best.
