When I was a child, I spent more than ten years learn the violin. Therefore. I couldn't understand “real music”· After I graduated from high school, the friend of mine suggested that we started to learn the guitar because we all thought it was cool. I will never forget the day on that we went to buy guitars in the guitar store. Here I saw a guitar player playing the guitar, which I really enjoyed. He became my first guitar teacher. There were too many wonderful models to choose that it took me a long time to buy one Now the guitar is the most importantly part of my life and I practice it every day.
