Twelve-tone rows that are invertible with all different intervals
These patterns are all-interval series (AIS) - twelve-tone rows containing all 11 different intervals. They can be inverted around an axis while maintaining musical coherence.

ALL-INTERVAL SERIES (AIS)
These twelve-tone rows contain all 11 different intervals (m2, M2, m3, M3, P4, TT, P5, m6, M6, m7, M7). They are "invertible" - meaning they can be inverted around an axis and maintain musical coherence. Slonimsky catalogued 18 fundamental types in 1947, predating much of the academic research on all-interval rows.
