I wish I knew how to play guitar
I have never learned either. Guitars are fretted instruments usually with six strings.
I just love the sound
Me too. Classic guitars produce sound from a hollow cavity in the guitar body.
Electric guitars sound pretty cool, but I would want a classic
Yeah, they sound better to me as well. They are played by strumming and plucking the strings with your fingers, or using a pick.
It seems like it would be difficult to learn
I think you're right, at least until you get the hang of it. The tone is produced by the string vibration, amplified by the body of the guitar.
