Here is a definition I am using in a Sloane integer sequence entry; it
would be nice to have a Tonalsoft entry on "Pepper ambiguity" to link to.

We may define the p-limit Pepper ambiguity, for any odd prime p, as
the maximum of the ratios of the errors of the nearest approximation
to the members of the p-limit tonality diamond to the next nearest. In
the 5-limit, that means we look at the ratios of the errors for the
nearest approximations to 3/2, 5/4 and 5/3 to the next nearest. The
concept was proposed by Pepper Keenan.

That's Keenan Pepper.

Sorry, this should say "any odd number greater than one" not "any odd
prime".

We may define the n-limit Pepper ambiguity, for any odd number n
greater than one, as the maximum of the ratios of the errors of the
nearest approximation to the members of the n-limit tonality diamond
to the next nearest. In the 7-limit, that means we look at the ratios
of the errors for the nearest approximations to 3/2, 5/4, 5/3, 7/4,
7/5 and 7/6 to the next nearest. The concept was proposed by Pepper
Keenan.

Duh. Right you are. Why does the world contain a Pepper Keenan and a
Keenan Pepper, anyway?

Sorry, Keenan.
