Chapter 2, “Objects and Entities,” provides a rigorous look at the concepts of pitch, pitch class, intervals, pc set, and the interval content of sets. class set theory’s conceptualization of musical structure” (27). Download PDF Abstract: The purpose of this paper is to show through particular examples how group theory is used in music. If anything they are often trying to break them! (Caution: sometimes ⊂ is used the way we are using ⊆.) Ling 310, adapted from UMass Ling 409, Partee lecture notes March 1, 2006 p. 4 Set Theory Basics.doc 1.4. Modes have been used in music long before the Western world started to favour harmony, and settled for the major and minor scales. we can do the this with math by taking all non-zero numbers and subtracting them from 12. the original set when inverted, becomes normal form the normal form of a set is the most compact ordering of the set. Compare this to the concept of modes of limited transposition found in Messiaen’s theory. set of rules. music theorists don’t create rules for writing music; they look for patterns in music that is already written. Schuijer begins the chapter thus: “Pitch-class set theory is a musical application of mathematical set theory… ... An art collector might own a collection of paintings, while a music lover might keep a collection of CDs. in the set, or half that number in the case of the tritone, then the set will be transpositionally symmetrical. It is natural for us to classify items into groups, or sets, and consider how those sets overlap with each other. Musical Composition as Applied Mathematics: Set Theory and Probability in lannis Xenakis's Herma 143 Xenakis lends structure to the set-theoretic procedures by defining two sequences of operations that lead to an identical fmal set, F, whose contents are represented by the Venn diagram in Figure 1. Set. Any collection of items can form a set. 2 Basic Group Theory 1 Introduction In 2002, a music theorist by the name of Julian Hook published a paper in the Journal of Music Theory titled, \Uniform Triadic Transformations." 2. set theory as it is theorized and applied by Allen Forte. Subsets A set A is a subset of a set B iff every element of A is also an element of B.Such a relation between sets is denoted by A ⊆ B.If A ⊆ B and A ≠ B we call A a proper subset of B and write A ⊂ B. Most other popular musical systems in the world are still mostly modal. Staff (or Stave) - a set of 5 lines (and 4 spaces between those lines) that music notes and symbols are written or printed on. For example, D, F, A# is (2, 5, T). which leads to … that music not es and symbols are written or printed on. 4. Set Theory. A set is any unordered group of unique (no-repeats) pitch classes. I consider set theory to be one of the most important theories in the history of music analysis in the Twentieth Century: it offers an analytical model of a particular musical style, namely atonal music, for which Modes can be defined at will, and don’t have to be based on seven notes; this just happens to be the most useful set in Western music. Inversional Symmetry This is a property of a set which is able to map onto itself through inversion at some value of n. If the intervals between To transpose a set up by n half steps, add n to each pitch class in the set. In this paper, Hook generalized some existing music theoretical concepts and greatly improved their notation. To transpose a set down by n half steps, subtract n from each pitch class in the set. The examples are chosen from the theoretical work and from the compositions of Olivier Messiaen (1908-1992), one of the most influential twentieth century composers and pedagogues. in set theory, inverting a set means flipping it upside-down. Two so while a lot of people think music theory is about learning the rules for how to write music, that’s not quite right. 3. Treble Clef (or G Clef) - a clef that wraps around the second line from the bottom of the staff, showing that this line is where the note “G” is found. 1.
