i like guitar 
Are you referring to the fretted musical instrument?
yes

Really?
Yes, it is typically played by strumming or plucking the various strings so you have to be precise
I like the sound of guitar 
Thats because the guitar is a type of chordophone which makes sounds pleasant to the human ear.
Yes it is
I also own a Vivette, which is the four-course Renaissance guitar, its very expensive!
