Where these facts come from

Every value on this page is derived from the note formula for a major 7th 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.
