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