What A5 is made of
A5 (A power) is built from the notes A, E, with the interval pattern 1, 5.
Stack 1 and 5 on a root of A and you get A and E. That interval recipe is what makes the chord a power chord — move the same shape to another root and the character travels with it, which is why C5 sounds like a transposed A5.
