How Ddim7 is built

Ddim7 is a diminished seventh: three minor thirds stacked, so the chord divides the octave into four equal parts. That symmetry means Ddim7 contains exactly the same four notes as Fdim7, G♯dim7 and Bdim7; which name you use depends on the bass note and the key.

Start on D, count 3 half steps up to F, 3 half steps up to A♭ then 3 half steps up to C♭.
