The rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.
The fundamental concept of musical set theory is the (musical) set, which is an unordered collection of pitch classes. [4] More exactly, a pitch-class set is a numerical representation consisting of distinct integers (i.e., without duplicates). [5]
The Oxford Companion to Music describes three interrelated uses of the term "music theory": The first is the "rudiments", that are needed to understand music notation (key signatures, time signatures, and rhythmic notation); the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology ...

Seems the value of a perch varied from 18-24' in the 1300's, and even in 1820, was between 16.5 and 25'. See the talk page at perch (area).I feel it would serve better to move the perch length info to a unified perch page that encompasses both length and area definitions, reflecting at least 600 years of use, and perhaps even explaining how one got to include the other, with a link here to ...
Theory, even of music of the common practice period, may take other forms. [155] Musical set theory is the application of mathematical set theory to music, first applied to atonal music. Speculative music theory, contrasted with analytic music theory, is devoted to the analysis and synthesis of music materials, for example tuning systems ...
I grew up in Dubai but moved to New York for college in 2022.. New York and Dubai are bustling metropolitan cities, and surprisingly, they share many similarities. But I miss my friends and family ...
The result is a cyclical quotient group that music theorists call pitch class space and mathematicians call R/12Z. Points in this space can be labelled using real numbers in the range 0 ≤ x < 12. These numbers provide numerical alternatives to the letter names of elementary music theory:
