Key Signature
A chord has no key signature of its own, but the D Major is the tonic (I) chord of D Major, whose key signature has 2 sharps (F♯, C♯).
Order of sharps
Sharps are added to a key signature in a fixed order. Each new sharp key adds the next sharp on the list.

Where these facts come from
Every value on this page is derived from the note formula for a major applied to the root D, 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.
