A software tool designed for musical analysis employs set theory principles to examine relationships between pitches. This type of tool can determine intervallic content, normal form, prime form, and other set-theoretic properties of a collection of notes, often providing visualizations and comparisons to aid comprehension. For example, entering the pitches C, E, and G would reveal the chord as a C major triad and display its set class membership.
Such analytical software provides musicians and composers with a powerful means to understand the underlying structure of musical works. This facilitates deeper analysis of existing compositions, aids in the exploration of new harmonic possibilities, and supports the development of complex musical structures. Historically, manual calculation of these properties was a laborious process. These digital tools democratize access to advanced music theory concepts, fostering wider engagement with and understanding of them.
