We can use the Circle of 5ths to test our fluency across the fretboard. Let's check it out.
How does the Circle of 5ths apply to practice?
Well, when we move up a 5th (7 frets) up the fretboard, we move one step clockwise around the note wheel.
When we move a 4th (5 frets) down the fretboard, we move one step counter-clockwise.
If we repeat that 12 times, we hit every note along the way and end up back in the same spot.
Find a C note on the low E now, and try moving downwards in 4ths. You will quickly run out of space to move downwards and need to use octaves.
Now try it the other way, moving upwards by 5ths. Again, you will need to use octaves to keep from running off the end of the fretboard!
Were you able to figure it out? This is the basic idea behind Circle of 5ths cycling.
Now, we can apply this idea to any scale, chord or arpeggio shape!
The purpose of this exercise is to build confidence playing your shapes in every key, and to get you comfortable working with octaves and jumping around the fretboard.
Here it is applied to a Major Chord shape, moving upwards by 5ths. I used octaves to keep it in a comfortable range. Notice how it almost looks like we're moving downwards by 4ths because of the octave jumps.
My favorite way to use this, though, is with a new arpeggio shape I'm working on memorizing.
For example, here is the C Shape Arpeggio moving downwards by 4ths. Again, it can be a little confusing to keep track of the movements because of the octave jumps, but try to make sense of it!
Once you're comfortable with the concept, this is a pretty good way to get warmed up across the fretboard, or to bulletproof your memorization of a new shape.
It's a little confusing at first, but stick with it. This will grow your playing ability in more ways than one!
