In becoming an adept guitar player it is important to master the fretboard, learn all the notes on the guitar, and be able to move freely around the neck and play all your scales, riffs, licks, chops and solos in every key.

You can cultivate this by using and practicing your musical ideas through the cycle of fourths. For in depth explanation of the cycle of fourths check out How to Benefit from The Circle of Fifths and Fourths. In this post we are going into the practical side of things.
