Guitar solos can get boring when they only use one rhythm. One way to spice up your solos is to play different rhythms while in your guitar solo and improvisation. This is a great exercise to help you learn to switch rhythms while playing lead guitar.
So grab your metronome and watch this video and soon you will be able to switch your rhythm with ease. This lesson uses the A major scale. Also note that i am using alternate picking while I play. If you have any questions please post them to the comments and I will do my best to answer them!
