Difference between classical and jazz music anyone?

Classical guitar strings are of nylon rope, while jazz guitar strings have steel wire, which determines the different tones of the two!

The style of the song, classical simple, solemn, rigorous, basically according to the score interpretation, as long as a lot of practice on the line. And some genres of jazz are basically tuneless music, talking about the whole, music bars can be free to play. Free improvisation is the root of jazz, from this point of view, jazz guitar to be more difficult than the classical guitar, good jazz guitarist are often also composers!

Classical tunes may be hummable by the average person, but traditional jazz is hard to hum without some jazz foundation. Perhaps the jazz you learned was Smooth Jazz, a blend of popular tunes that is still quite suitable for modern people, and it's not hard to get started.
