Abstract Voice-Leading Space Builder

After Morris (1998) — enter two pcsets and permissible intervals to check connectivity

Set A (source)

Pitch-class set

Set B (target)

Pitch-class set

Permissible pitch-class intervals (pci)

Select all Clear all

Definitive (all pcs of A and B present) R3 (homorhythmic, no rests)

▶ Compute Voice-Leading Space

▶ T-matrix (A → B)

Based on: Robert D. Morris, "Voice-Leading Spaces," Music Theory Spectrum 20/2 (1998): 175–208. T-matrix algorithm (§ Constructing Voice-Leading Spaces, pp. 203–205); voice-leading restrictions R1–R3 and definitive VL (pp. 178–180).
