I've always wanted to learn to play guitar, but I'm quite intimidated by it
It can be especially when you realize that there are 3 types of modern guitars. The classical guitar, the steel-string acoustic guitar, and the arch top guitar
Wow. I had no idea. Do you play each of them differently? 
They have different frets. The classical guitar has 12 frets while the steel string guitar has 14
Oh cool. And what is a fret? 
A fret is raised portion of a stringed instrument. 
Do the three types of guitars make different music? 
They are basically played the same way. When you strum the strings, the vibration is amplified by the body of the guitar which acts as a resonator.
