Major Scales for Guitar are very common and it is truly worth your while learning them. They are not necessarily the absolute best for improvisation, they are useful to help train your ears and to learn what notes fall into particular keys. I have listed five of the essential ones in the Keys of:
C, G, D, A, and E
Practice them slowly and carefully, concentrate on tone and listen closely. After a period of time playing guitar, you’ll end up being able to automatically hear a note and play it. I recommend quietly humming the notes as you play them, this will help you develop the skill of playing what you hear in your head.
