Key Signature
A Suspended 2nd chord is built from symmetrical or ambiguous intervals, so it doesn't belong to a single key and has no key signature of its own.

Spans are measured centre to centre at a 165 mm octave (standard keyboard geometry).
| Position | Bass note | Notes in order | Figured bass | Semitones | Span |
|---|---|---|---|---|---|
| Root position | G | G3, A3, D4 | 5/3 | 7 | 96 mm |
| First inversion: Gsus2/A | A | A3, D4, G4 | 6/3 | 10 | 138 mm |
| Second inversion: Gsus2/D | D | D4, G4, A4 | 6/4 | 7 | 96 mm |
One position per chord tone in the bass. Spans are for close position: voiced inversions appear under Voicings.

Where these facts come from
Every value on this page is derived from the note formula for a suspended 2nd applied to the root G, using standard music theory. Nothing here is hand-entered per chord, so the notes, intervals, inversions and frequencies cannot drift out of agreement with each other. Pitches assume 12-TET at A440.
