Webpitch class is a group of pitches that is related by transposition or inversion. Interval vs. interval class : An interval has a specific distance in semitones, while an interval class is a group of intervals that are inversions of each other or related by octaves. Introduction In musical set theory, pitch-class intervals do not distinguish between octaves since pitch-classes themselves treat all octaves as being equivalent. There are two kinds of pitch-class intervals: • ordered pitch-class interval (also called a pitch-interval class - PIC) • unordered pitch-class interval (also called an 'interval class')

WebThe ordered pitch-class interval is also the modulo12 version of the ordered pitch interval. For example, B4–G4 is –4 semitones (4 semitones down). mod12(–4) = 8. C3–D4 is 14 semitones. mod12(14) = 2. pitch – A pitch class in a specific register, such as C4 (middle C). WebPitch intervals Closest to our aural experience is the concept of ordered pitch intervals: we hear intervals of a particular size and direction between successive pitches. One pitch, for instance, might be 9 semitones above the previous one, or 15 semitones below. incline house theatre

WebFind the largest ordered pitch-class interval between adjacent pitch classes. In this case, the largest interval is between “9” and “3.” Rewrite the collection beginning with the pitch … WebPitch-class orderings are not the only things ordered by twelve-tone rows. Because pitch classes are always in relationships with one another, a twelve-tone row is also an ordered collection of intervals. Understanding the intervallic structure of a row class is the best way to get a sense of what it will sound like. WebOct 1, 1991 · Example 5. Different contour, but the same ordered pitch-class intervals. The contours of the two fragments (their ordered pitch intervals) are different, but the ordered pitch-class intervals are the same: 9-11-3. This similarity is a nice way of rounding off the melodic phrase and of reinforcing the rhyme in the text: "Wie bin ich froh ... incline ice tie dye
