The PC Set Calculator analyzes sets ranging from three to twelve pitches and provides: * Forte name * Normal form * Prime form * IC Vector * Z-Mate * Tn Invariance * TnI Invariance The calculator also will provide the inversion and complement sets with all the above information and all sets can be analyzed for subset and superset relationships (a very handy tool when analyzing Webern!). **WHAT’S NEW!!!** The Matrix Calculator will generate a matrix with any number of pitches up to twelve. The rows are numbered using the Straus/Roig-Francoli system (Introduction to Post-Tonal Theory/ Understanding Post-Tonal Music), where the P and I row labels correspond to the starting pitch class. Any number of pitch classes within the matrix can be highlighted and the selected set then sent back into the PC Set Calculator. This feature is extremely helpful when comparing trichords, tetrachords, and hexachords!
