'''Beep''' is a remarkable low-complexity, though high-badness [[7-limit]] [[temperament]]. It is also called '''titanium''' by [[Mason Green]]. It [[tempering out|tempers out]] the [[21/20|septimal minor semitone (21/20)]], making it a [[septisemi temperaments|septisemi temperament]], and the [[49/48|slendro diesis (49/48)]], making it part of the [[slendro clan]]. As such, [[6/5]], [[7/6]], and [[8/7]] are all represented by the same interval (which, in fact, is the [[generator]]). Two of these generators make a very sharp [[4/3|fourth]] (which is also a very flat [[7/5]]). Since three fifths make a minor (not major) sixth, and four make a minor (not major) third, it is also similar to the [[pelogic]] temperament ([[superpelog]] in particular). It also tempers out [[27/25]] and is part of the [[bug family]]; because of this, the generator also functions as [[10/9]] (meaning this tuning has a ''negative'' syntonic comma). Finally it can be also considered a sort of messed-up variant of [[orwell]] temperament as well, since the generator falls into the same range of sizes.

Two fifths make a second that is neutral in [[interval quality|quality]], so a good tuning typically has a ''negative'' [[syntonic comma]]. Since three fifths make a sixth that sounds minor, and four make a third that sounds minor, it is also similar to the [[pelogic]] temperament ([[superpelog]] in particular). Finally it can be also considered a sort of messed-up variant of [[orwell]] temperament as well, since the generator falls into the same range of sizes.


The edos whose [[patent val]]s support beep are [[4edo]], [[5edo]], [[9edo]], and [[14edo]]. Many other edos can be used as non-patent vals, such as 13.

If using brittle titanium (23cd, 14edo, etc.), one might want to consider using this as a guideline. With this spectrum, no partials are more than 25 cents above or below their perfectly harmonic values, and when using 14edo, no intervals will be more than 26 cents out of tune. This is only a guideline, and only with synthesized tones would it be possible to achieve this perfectly. With physical idiophones (celestas, gamelans, etc.) it should still be possible to get a great approximation using CAD (or trial and error).
