As you're learning guitar, you'll likely hear players reference the CAGED system as being a great tool to utilize in your learning process. To put it simply, CAGED is essentially a way of visualizing chord shapes on the fretboard. The trick to using the CAGED system is to realize that it consists of moveable shapes that can be any chord depending upon where you put the root note. The letters C-A-G-E-D refer to the open chord shapes.
In this series of videos, Guitar Tricks instructor Mike Olekshy will show you the ins and outs of the CAGED system and how you can apply it to your playing.
