Atonal Assistant
A Web-based software application that performs basic pitch-class set calculations and operations. Written with the set-theory novice in mind, the program was specifically designed for compatibility with Joseph Straus' Introduction to Post-Tonal Theory, 3/e and Kostka/Payne's Tonal Harmony: With An Introduction to Twentieth-Century Music, 6/e. Students and instructors alike may use the program to check answers to textbook and workbook exercises, check their own theoretical calculations, or freely explore the pitch-class set universe.

Twelve-Tone Assistant
A Web-based software application that performs basic 12-tone operations and generates matrices useful in the analysis of twelve-tone music. Matrices may be generated using fixed-zero or movable-zero notation. Written with the 12-tone theory novice in mind, the program was designed for compatibility with Joseph Straus' Introduction to Post-Tonal Theory, 3/e, Joel Lester's Analytical Approaches to Twentieth-Century Music, and Kostka/Payne's Tonal Harmony: With An Introduction to Twentieth-Century Music, 6/e. Students and instructors alike may use the program to check answers to textbook and workbook exercises, check their own theoretical calculations, or freely explore the 12-tone universe.

SLAPI
String Length and Pitch Interval (SLAPI) is a just interval player. It provides students of tuning theory with an easy way to compare just pitch intervals with their equal-tempered counterparts on the modern piano. SLAPI will be of interest to music students who are encountering the harmonic series or just intonation for the first time. It may also be of interest to K-12 math teachers who are looking for a simple way to sonifiy fractions, that is, to demonstrate what fractions sound like in the musical domain.
