What is a set class in music theory?
A set class is a group of pitch class sets related by transposition or inversion. Set classes are named by their prime form . Prime form is the version of the set that is transposed to zero and is most compact to the left (compared with its inversion.) You can find prime form mathematically or by using the clock face.
What is a forte name?
Italian: from the personal name Forte, from Late Latin fortis ‘strong’ (see Fort) or from a short form of a medieval personal name formed with this element, as for example Fortebraccio (‘strong arm’). Slovenian: shortened form of the personal name Fortunat, Latin Fortunatus. English: variant of Fort.
How many set classes are there?
The number of distinct sets in a type is 24 (the total number of operations, transposition and inversion, for n = 0 through 11) divided by the degree of symmetry of T n /T n I type.
How many pitch classes are there in music?
twelve pitch classes
There are twelve pitch classes, one for each note in the chromatic octave. Enharmonic Equivalence Any enharmonic spelling of a pitch class is considered to be equivalent; that is, B = C, E = F , or C = D . Thus, C and D are members of the same pitch class.
Is Forte a pitch?
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 0-300-02120-8).
How do you write Prime in music theory?
Compare the normal form (transposed to 0) to the most compact inverted form (transposed to 0). The most compact form is the prime form. Prime form is written in parentheses with no commas: (0148).
What is Forte number in music?
What is Allen Forte’s set theory?
Allen Forte’s Set Theory, Neutral level analysis and Poietics can be reduced to its root position and to the same function (tonic, dominant, etc.), it was possible for Forte to reduce the diversity and the multitude of all possible atonal sonic manifestations to a number of basic entities, 208 of them to be exact.
What is a Forte number?
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 0-300-02120-8 ).
Why are there two different normal form sets for Forte numbers?
“T” and “E” are conventionally used in sets to notate 10 and 11, respectively, as single characters. There are two slightly different methods of obtaining a normal form. This results in two different normal form sets for the same Forte number in a few cases. The alternative notation for those chords are listed in the footnotes.
Is Allen Forte’s analysis relevant to Schoenberg?
Allen Forte’s Set Theory, Neutral level analysis and Poietics Forte’s empirical observations are not what justifies the poietic relevance of his analy-sis. It is in fact his preconceived notions a priori about Schoenberg’s poietics which lead him to legitimate his analytical procedure.
