Drum notation:

A drum kit is a form of percussion. Percussion (unless it is tuned) can't really be written down. So drummers use a different type of notation in order to write down their parts. 

In order to understand drum notation you must have an understanding of what a drum kit looks like and the names of each part of the kit. Have a look at top left picture which shows a basic drum kit layout.  

What does drum notation look like?: Drum notation uses the same staff format as traditional music notation. Drum notation also uses the same tempo, dynamic, rhythm and bar markings. The only difference is the lack of a key signature and a different clef marking as seen on the bottom left image.
