3.10. pctheory.set_complex
This module contains functions for working with Allen Forte's set-class complexes K and Kh. At present, there are only functions for determining whether or not two set-classes are K‐ or Kh‐related. It is easy to generate a complete K or Kh corpus by considering all 224 set-classes in the chromatic system, but this is impractical in the microtonal system due to the huge number of set-classes.
assert_k(s, t)bool
Asserts that set-classes s and t are in a K‐relationship. Returns True or False.
assert_kh(s, t)bool
Asserts that set-classes s and t are in a Kh‐relationship. Returns True or False.
get_k12(nexus: SetClass12)[SetClass12]
Generates the set-complex K about the provided nexus set.
get_kh12(nexus: SetClass12)[SetClass12]
Generates the set-complex Kh about the provided nexus set.
