E♭ Major in detail

Exact

Every pitch class is present and nothing outside the chord is added.

Close, first inversion	G3 B♭3 E♭4	8	110 mm	none	identical

A subset of the pitch classes: the identity is incomplete rather than altered.

Spans are measured centre to centre at a 165 mm octave (standard keyboard geometry).

Where these facts come from

Every value on this page is derived from the note formula for a major applied to the root E♭, 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.
