Metrical tree
PHONOLOGY: a branching representation of stress, introduced by Liberman & Prince (1977), see also metrical phonology. A metrical tree is a hierarchy in which syllables are combined into feet and feet into a word constituent. Higher level structure includes the phonological phrase, intonational phrase and utterance (cf. Selkirk (1981), Nespor & Vogel (1986)). Pairs of sister nodes are labeled Weak-Strong or Strong-Weak (or by the Lexical Category Prominence Rule). The English phrase achromatic lens is represented as follows:
/ \
/ \
/ \
/ \
w s
/ \ | where S = syllable, w = weak
Fw Fs F F = foot, s = strong
/ \ / \ \
Ss Sw Ss Sw S
| | | | |

Hayes (1981) constrained metrical theory considerably by the introduction of a universally defined set of
parameters that characterize the stress systems
of languages (i.e. bounded/unbounded;
dominance (left/right), direction of footing,
quantity-(in)sensitivity).
