In the imperial measurement systems, "pitch" is usually expressed with the rise first and run second (in the US, run is held to number 12; [1] e.g., 3:12, 4:12, 5:12). In metric systems either the angle in degrees or rise per unit of run, expressed as a '1 in _' slope (where a '1 in 1' equals 45°) is used.

'CATSLIDE ROOF. A roof with one side longer than the other, continuing at the same pitch over an extension to a building.' The illustration of roof pitches is helpful but the labeling on each little house is in opposite format than the descriptions used in the rest of the article. In other words the 5/12 pitch roof is labeled 12/5.----
[1] In equal temperament, all the semitones have the same size (100 cents), and there are twelve semitones in an octave (1200 cents). As a result, the notes of an equal-tempered chromatic scale are equally-spaced. The chromatic scale...is a series of half steps which comprises all the pitches of our [12-tone] equal-tempered system.
(An overtone may or may not be a harmonic) [1] In other words, overtones are all pitches higher than the lowest pitch within an individual sound; the fundamental is the lowest pitch. While the fundamental is usually heard most prominently, overtones are actually present in any pitch except a true sine wave . [ 2 ]
Thus, a 12-note chromatic scale adds 5 pitch classes in addition to the 7 lettered pitch classes. The following chart lists names used in different countries for the 12 pitch classes of a chromatic scale built on C. Their corresponding symbols are in parentheses. Differences between German and English notation are highlighted in bold typeface ...
Comparison between tunings: Pythagorean, equal-tempered, quarter-comma meantone, and others.For each, the common origin is arbitrarily chosen as C. The degrees are arranged in the order or the cycle of fifths; as in each of these tunings except just intonation all fifths are of the same size, the tunings appear as straight lines, the slope indicating the relative tempering with respect to ...
