What G7 is made of
G7 (G seventh) is built from the notes G, B, D, F, with the interval pattern 1, 3, 5, b7.
Stack 1, 3, 5 and b7 on a root of G and you get G, B, D and F. That interval recipe is what makes the chord a seventh chord — move the same shape to another root and the character travels with it, which is why C7 sounds like a transposed G7.
