the violin is qite cool
I agree! It is sometimes called a fiddle, and is made of wood. The sound is very unique.
oh thats interesting
Yes! They also usually have a hollow wooden body. It helps the sound resonate.
thats pretty awesome, what else?
Well is has the smallest and highest pitched sound in its family of instruments. 
oh really one of the smallest? Thought it was quite decently sized
Yes it's true. They usually have 4 strings that are tuned to perfect 5ths, and you play it with a bow.
thats cool, thanks for the info
You're welcome. The violin is an important instrument and is used to play a large variety of music.
