The book “Palindromorphy” deals with the symmetries of the keyboard (softcover book click here; eBook click here).
Though in piano pedagogy it is relatively common for the central white key D and the black key Ab / G# to be named as mirror axes of the keyboard, no detailed investigation of the creative applications of this phenomenon in improvisation and composition has yet been carried out. The book is primarily aimed at pianists and composers who are inspired by music-theoretical considerations and at the same time wish to gain insight into creative implementations.
