WebA collection of all 12 pitch classes. The term generally refers to the combination of two or more 12-tone rows to generate new 12-now collections. Aggregates may also appear in non 12-tone music. Atonal/ Nontonal Music that freely employs all 12 pitch classes. Ordered Pitch Interval The ordered pitch interval. is the number of semitones that separates one pitch from another, upward or downward. It is thus more specific than the unordered pitch interval in that it represents the directionality of the interval. An ordered pitch interval always includes a plus or minus sign. Thus … See more In musical set theory, there are four kinds of interval: • Ordered pitch interval • Unordered pitch interval • Ordered pitch-class interval See more Using integer notation and modulo 12, ordered pitch interval, ip, may be defined, for any two pitches x and y, as: • and: See more • Interval class See more In musical set theory, pitch-class intervals do not distinguish between octaves since pitch-classes themselves treat all octaves as being equivalent.

WebWhat is an ordered pitch interval (opi)? They include both the direction and distance between the pitches, (-3, +16). + = ascending - = descending What is an unordered pitch interval? It includes the distance between two pitches but NOT the direction. Discuss ordered pitch class intervals. The unordered pitch class interval i(a, b) may be defined as where i⟨a, b⟩ is an ordered pitch-class interval (Rahn 1980, 28). While notating unordered intervals with parentheses, as in the example directly above, is perhaps the standard, some theorists, including Robert Morris (1991), prefer to use braces, as in i{a, b}. Both notations are considered acceptable. danish language courses us university
