Shown on the right is what makes up a basic drum kit, it contains:

• A bass drum or foot bass, this is the largest drum in the kit and is operated by a pedal.
• cymbals; usually a crash, a ride cymbal, and a hi-hat cymbal, however more cymbals can be added on to produce more drum patterns. the hi-hat is opened and closed using a pedal.
• tom-toms; which includes the regular tom-toms placed on top of the bass drum and the floor tom. 
• and lastly, the seat!

Why I chose Drums for my creativity in CAS:

I feel that the drum kit is one of the best intruments ever made by man! It is probably the only musical instrument that requires the use of all four limbs and it's various sounds make up the core of every song made regardless of whether it is a rock song or a modern hip-hop/pop song (the single beat of the bass drum is digitally inputed in to a computer to make it sound deeper and louder). I feel that by learning how to play this instrument, I will literally be in control of the songs if I play in a band consisting of other intruments and therefore, such a intrument MUST be mastered.
