Moving the E Shape
We can use a piece of the E chord shape as a basis to build 11 other chords [we can also use the entire E shape].
The piece we are using is the root and the 5th of the chord, played together. We take a piece of E [6 and 5 strings], move the shape onto the board, and now it’s movable to 11 other locations. These shapes are sometimes referred to as ‘power chords‘.
This shape also works down a string level – 5 & 4 strings. These would be R5s based on the A form. The roots will be in different places however [think 5-0 tuning – the A5 in P5 for E, starts the cycle on the A string]. And, the shape works again on the 4 & 3 strings – these would be based on the D form.
