Connections To Set Theory
Musical set theory uses some of the concepts from mathematical set theory to organize musical objects and describe their relationships. To analyze the structure of a piece of (typically atonal) music using musical set theory, one usually starts with a set of tones, which could form motives or chords. By applying simple operations such as transposition and inversion, one can discover deep structures in the music. Operations such as transposition and inversion are called isometries because they preserve the intervals between tones in a set.

Famous quotes containing the words connections, set and/or theory:
“A foreign minister, I will maintain it, can never be a good man of business if he is not an agreeable man of pleasure too. Half his business is done by the help of his pleasures: his views are carried on, and perhaps best, and most unsuspectedly, at balls, suppers, assemblies, and parties of pleasure; by intrigues with women, and connections insensibly formed with men, at those unguarded hours of amusement.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“In the lack of judgment great harm arises, but one vote cast can set right a house.”
—Aeschylus (525–456 B.C.)
“By the “mud-sill” theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be—all the better for being blind, that he could not tread out of place, or kick understandingly.... Free labor insists on universal education.”
—Abraham Lincoln (1809–1865)
