This last chapter is, on the one hand, a sightseeing tour of a selection of the most beautiful geometrical models of musical spaces, developed mostly in the late 20th century. On the other hand, it introduces, hopefully painlessly, to vector and quotient spaces, group products, the Tonnetz and its dual, the chickenwire, and several Möbius strips and Torii pertinent to music studies. A postface by the past vice-President of the Society for Mathematics and Computation in Music stresses the usefulness of the whole book. Solutions (or at least hints) are provided for the numerous exercises.
