You know that you need to learn guitar scales so that your guitar playing, whether you play rock guitar or jazz guitar or even Country guitar, improves dramatically. You want to sound fluid and creative, not formulaic; you won’t want to play the “same ol’ same ol’”. When you learn guitar scales you’ll take your guitar playing even higher with the learning of modes. Modes are simply variations upon guitar scales that, when played in certain ways, cause the music to take some dramatic turns. If you learn guitar scales as well as modes, you will be far ahead of those who only learn one, or don’t learn any, of these things.
