What are the different drum setups commonly used by drummers?

Drummers commonly use different drum setups such as the 4-piece, 5-piece, and 7-piece drum kits. The 4-piece setup includes a bass drum, snare drum, and two toms. The 5-piece setup adds a floor tom to the 4-piece configuration. The 7-piece setup includes additional toms and cymbals for more versatility in playing.
