Now on to the lead playing! The lines in this solo etude are based around both the E major (nicer sound) and minor (dirtier, bluesier sound) blues scales. They lead you through several positions over the neck, use different type of rhythms as well as a few important clichés, such as the bending lick in the fourth bar.
Be sure to check out all the other Infinite Guitar material on the pentatonic and blues scales. For any type of question regarding this, be sure to contact me through the site’s forum. Good luck on your blues journey!
