Have you ever seen how the strings on your guitar vibrates?

My friend came across this video on Youtube today and share it with me. It's really interesting to see how the string vibrates to create different frequencies. However, notice that the thicker strings actually vibrate longer than the thinner strings. Hence the idea that strings of thicker gauge increase the sustain of your notes. This is a very interesting yet educational video. Do take some time off and look at the video.
