B863 <=> B865 (BTG XL Heptaparaparshinokh, p. 864)

“’Restorials’ or gravity-center-sounds in the voices of beings are in general and are called those notes which, during the reproductions of different sounds by corresponding organs, the beings manifest according to the properties fixed in them and depending on the general functioning of their presence – which properties in their turn are the result of heredity and of acquired faculties – freely, easily, and for a long time, without evoking any tension whatsoever on the part of other separate functionings of theirs, that is to say, in other words the restorials are obtained when the tempo of the result of such a manifestation of theirs fully harmonizes with other functionings of their common presence, the tempo of which is already fixed in them thanks to all the inner and outer conditions of their common being-existence.

“Thanks to the various conditions there of local character and also to various assimilated hereditary qualities, various ‘restorials of voice’ or gravity-center notes are formed in beings of almost each group or of each geographical place, and hence the division of the octave into whole notes among beings who breed on each definite part of the surface of this planet of yours is quite different.

“At the present time among your favorites such groups exist as have the capacity to reproduce the gravity-center notes in the octave of sounds not only in five or seven gravity-center sounds but even in thirteen and seventeen whole notes.

“To illustrate what I have just said, the beings of a certain smallish group might serve as a good example who dwell on the continent Asia to whose singing I personally very much liked to listen and who in their physiological possibilities – although they had the data for the manifestation of only three restorials – could nevertheless in their chanting reproduce up to forty separate definite sounds.
