Post-Tonal Theory Calculator
The Post-Tonal Theory Calculator is a versatile tool designed for musical set theory analysis and composition. With this app, users can define pitch class sets and perform various set theory operations on them. The app provides several features to facilitate analysis and composition, including calculating Normal Form and Prime Form, displaying the Forte Number, calculating the interval class vector, showing transposed and inverted sets, displaying a set matrix, and allowing users to sort, invert, or complement the set. Additionally, the app allows users to play the notes of the set as a melody or chord.
In addition to its practical functionalities, the app also provides a comprehensive written overview of musical set theory. This theoretical framework has been utilized by renowned composers such as Arnold Schoenberg, Alban Berg, and Anton Webern to organize the pitch content of their musical works.
