tnprime

Uses Rahn's algorithm to calculate the best normal order for the
transposition class represented by a given set. Reflects transpositional
but not inversional equivalence, i.e. all major triads return (0, 4, 7) and
all minor triads return (0, 3, 7).

Analysis of musical scales (& modes, grooves, etc.) in the vein of
Sherrill 2025 <doi:10.1215/00222909-11595194>.
The initials MCT in the package title refer to the article's title: "Modal
Color Theory." Offers support for conventional musical pitch class set
theory as developed by Forte (1973, ISBN: 9780300016109) and David Lewin
(1987, ISBN: 9780300034936), as well as for the continuous geometries of
Callender, Quinn, & Tymoczko (2008) <doi:10.1126/science.1153021>.
Identifies structural properties of scales and calculates derived values
(sign vector, color number, brightness ratio, etc.). Creates plots such as
"brightness graphs" which visualize these properties.
