This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

The 5-limit parent of the bug family is bug, a temperament of sorts (that is, an exotemperament) which tempers out 27/25, the large limma, approximately one step of 9edo. The monzo for 27/25 is [0 3 -2⟩.

Bug

The generator for bug is ~5/3, two of which give the ~3, and three of which give the ~5. Bug may be described as the 4 & 5 temperament, and its ploidacot is alpha-dicot. 14edo is a good bug tuning, though wide latitude in these matters is possible. 4-, 5-, or 9-note mos are a place to start with it. Another notable tuning of bug is given by TE, CTE and POTE, all coinciding at 939.612 ¢ with pure octaves since prime 2 is not involved in the comma to begin with.

Overview to extensions

Bug has an obvious 7-limit extension, beep, via the normal comma list {27/25, 36/35} which can also be obtained by adding 21/20. There is an alternative, mite, which adds 28/25 instead.

Temperaments discussed elsewhere include ugolino and codex. Considered below are beep and mite.

Beep

Main article: Beep
See also: Semaphoresmic clan

As bug divides 3/1 in half for 5/3~9/5, it only makes sense to also equate this interval with 7/4~12/7, joining the temperament with semaphore.

Beep has the curious property that if we know both the beep tempering and the ennealimmal tempering of a given 7-limit interval x, that is enough to know what JI ratio x is.
