This paper is an attempt to apply to the phonological hierarchy in particular views expressed recently by Pike (Pike, 1972) on the nature of linguistic hierarchies in general. In a paper presented to the 11th International Congress for Linguistics, Bologna, 1972, entitled Recent developments in tagmemics, Pike spoke of the possibility of developing ‘paired levels’ or a ‘paired ladder’ in a hierarchy. His main concern in that paper, and in a similar paper presented to the German branch of the Summer Institute of Linguistics, 1971, was with the grammatical hierarchy. It is my aim in this paper to show that ‘paired levels’, or ‘double ranks’ as I shall call them, apply equally well in the phonological hierarchy, and that they offer interesting possibilities of (a) developing the notion of interpenetration of hierarchies and (b) broadening the field of general theoretical categories of language.
