Here is a video representation of the post on playing the 3 Major scales ( B,Eb &G). Hum along whatever motifs you create it will create an illusion that you are making music and not just playing the scale or patterns.The more you play creatively the better you will get. I have always approached seemingly difficult tasks in simple blocks and try to own them. You must try as well :)
