How this entry was built

The notes, intervals, degrees and fingerings come from one stored spelling per entry, read by the site’s theory kernel. Nothing on this page is typed out entry by entry, which is why sibling keys agree with each other: they are the same arithmetic applied to a different root. What a person adds is the part arithmetic cannot settle, which is whether the spelling itself is the one a musician would write.

Whether a person has checked this entry

Not yet reviewed by hand. The data is kernel-derived and gate-checked, but nobody has signed it off.

How often anything gets checked

The data is checked most days. Every build runs the theory gates before anything ships, and the review count below is recounted at the same time, so it is current as of the last deploy rather than as of whenever someone last updated a number by hand.

1 of 1,548 chord and scale entries have been reviewed by hand (0.1%). Counted August 2026.
