This is a video tutorial on a short groove. I find this tutorial to be considered a bad one because the educator is in a costume which takes away from professionalism, the video quality is not the best, he does not show a slower break down of the groove he is playing, and there is no application as to where the groove would be played. It just demonstrates a quick groove for someone to randomly play and in my opinion seems a bit unprofessional for a tutorial video.
