Octaves are used all over the place in all types of music from popular to jazz. They create a very full yet airy sound when done correctly.
While you are watching this lesson, be sure to pay close attention the muting done by the fret hands first finger. Not muting all the strings that you aren't playing can cause a mess. 🙂
At the end of the video I demonstrate a way that you can create your own musical phrases using octaves and if you practice them like that it will be a lot more fun to you.
