One shape moved up 3 frets gives the next enharmonic root: C, E♭, G♭, and A dim7 are the same four notes.
About
The E fully diminished 7 (E–G–B♭–D♭) stacks four minor thirds, giving it a fully symmetrical structure. Each note can be respelled as a root — E°7 is enharmonically the same chord as G°7, B♭°7, and D♭°7 — meaning a single shape on the guitar can function as four different leading-tone chords depending on context. This flexibility makes dim7 especially useful as a passing or substitution chord, often resolving up a half step (here to F). All four tones carry the chord’s identity; the chord is defined by its symmetry, so removing any note weakens that quality. On guitar, one shape repeats identically every three frets. Compared to Em7♭5, dim7 is more unstable and dramatically tense.
