Many theories of intonational phonology have granted some special status
to pitch features that occur at the edges of prosodic domains, contrasting
them with prominence-lending pitch configurations. The standard
American structuralist theory that flourished in the 1950s (Trager &
Smith 1951) drew a clear distinction between PITCH PHONEMES and
JUNCTURE PHONEMES, the former constituting the body of a contour and
the latter describing the movements at the contour’s end. Parallel to this
development, a distinction was also drawn within the Prague School
between the cumulative and delimitative functions of tonal phenomena
(Trubetzkoy 1958), the former including prominence, the latter domainedge
marking. Bolinger (especially 1970) distinguished ‘accent’ from
‘intonation’: ACCENT referred to the distinctive pitch shapes that accompany
prominent stressed syllables (now generally known, following
Bolinger, as pitch accents), while INTONATION included, among other
things, distinctive pitch movements at the ends of contours. A distinction
very similar, but not identical, to Bolinger’s is made in the theory of
intonation developed at the Institute for Perception Research (IPO) in the
Netherlands (Cohen & ’t Hart 1967, ’t Hart et al. 1990), namely between
PROMINENCE-LENDING and NON-PROMINENCE-LENDING pitch movements.
