What Edim is made of
Edim (E diminished) is built from the notes E, G, Bb, with the interval pattern 1, b3, b5.
Stack 1, b3 and b5 on a root of E and you get E, G and Bb. That interval recipe is what makes the chord a diminished chord — move the same shape to another root and the character travels with it, which is why Cdim sounds like a transposed Edim.
Diminished: Tense, unstable; resolves outward.
Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with B♭ rather than its enharmonic equivalent.
