What E/3 is made of

E Major (1st Inversion) (E major (1st inversion)) is built from the notes G#, B, E, with the interval pattern 3, 5, 1. A common major (1st inversion) chord across many styles.

Stack 3, 5 and 1 on a root of E and you get G#, B and E. 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 F/3 sounds like a transposed E/3.
