In musical set theory, an interval vector is an array of natural numbers which summarize the intervals present in a set of pitch classes.
 (That is, a set of pitches where octaves are disregarded.)
 Other names include: ic vector (or interval-class vector), PIC vector (or pitch-class interval vector) and APIC vector (or absolute pitch-class interval vector, which Michiel Schuijer states is more proper.)

 Other notable stage appearances include Nora in the brief 2009 revival of Brighton Beach Memoirs and Daisy Fenton in the Off-Broadway run of Death Takes a Holiday.

In musical set theory, a Forte number is the pair of numbers Allen Forte assigned to the prime form of each pitch class set of three or more members in "The Structure of Atonal Music" (1973, ISBN  ).
 The first number indicates the number of pitch classes in the pitch class set and the second number indicates the set's sequence in Forte's ordering of all pitch class sets containing that number of pitches.
Spring Awakening is a rock musical with music by Duncan Sheik and a book and lyrics by Steven Sater.
 It is based on the German play "Spring Awakening" (1891) by Frank Wedekind.
 Set in late-19th-century Germany, the musical tells the story of teenagers discovering the inner and outer tumult of teenage sexuality.
 In the musical, alternative rock is employed as part of the folk-infused rock score.
Sam Levene (August 28, 1905 – December 28, 1980) was an American Broadway and film actor.
 He made his Broadway debut in 1927 with five lines in a play titled "Wall Street", and over a span of nearly 50 years, appeared on Broadway in 37 Shows, of which 33 were the original Broadway Productions, many now considered legendary.
 Levene made his film debut in 1936, recreating the role of Patsy that he had played in the Broadway production of "Three Men on a Horse" in 1935.
 He also appeared in the USO Tour of this same Show; the Radio Version; the Musical version that opened on Broadway called "Let It Ride" (1961) as well as the 1969 Broadway Revival of the play directed by George Abbott, the original Broadway Director and co-author.

In music, a tone row or note row (German: "Reihe" or "Tonreihe" ), also series and set, refers to a non-repetitive ordering of a set of pitch-classes, typically of the twelve notes in musical set theory of the chromatic scale, though both larger and smaller sets are sometimes found.
In music, a pitch class (p.c. or pc) is a set of all pitches that are a whole number of octaves apart, e.g., the pitch class C consists of the Cs in all octaves.
 "The pitch class C stands for all possible Cs, in whatever octave position."
 Important to musical set theory, a pitch class is, "all pitches related to each other by octave, enharmonic equivalence, or both."
 Thus, using scientific pitch notation, the pitch class "C" is the set
Musical set theory provides concepts for categorizing musical objects and describing their relationships.
 Many of the notions were first elaborated by Howard in connection with tonal music, and then mostly developed in connection with atonal music by theorists such as Allen , drawing on the work in twelve-tone theory of Milton Babbitt.
 The concepts of set theory are very general and can be applied to tonal and atonal styles in any equally tempered tuning system, and to some extent more generally than that.
