Post-Tonal Theory Calculator 1.0.4

The Post-Tonal Theory Calculator serves as a professional tool for musical set theory analysis and compositional reference. It allows users to define pitch class sets and perform a range of analytical operations commonly used in post-tonal composition and research.

For each pitch set input, the application provides:

• Calculation of Normal Form and Prime Form
• Display of the Forte Number classification
• Computation of the interval class vector
• Visualization of transposed and inverted variants
• Generation of a set matrix to illustrate relationships
• Options to sort, invert, or complement the set
• Playback functionality featuring the set as a melodic or harmonic element

Additionally, the app offers a thorough written overview of fundamental concepts in musical set theory. This includes historical context and techniques utilized by notable composers such as Arnold Schoenberg, Alban Berg, and Anton Webern in their approach to organizing pitch material through set theory methods.
