What C/E is made of

C/E (C major first inversion) is built from the notes E, G, C, with the interval pattern 3, 5, 1.

Stack 3, 5 and 1 on a root of C and you get E, G and C. 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 C/E.

Major (1st Inversion): Major triad with the third in the bass.
