Constraints Measure Metrical Intuitions
University of Toronto
In this presentation I demonstrate how recent constraint-based
theories in phonology and metrics (Golston and Riad 1996, Hayes and
MacEachern 1998) can be used to account for speakers' intuitions about
complexity of poetic meter.
It is well-known that speakers of a language have intuitions about
metrical well-formedness (Kiparsky 1975, Hayes and MacEachern 1998).
Moreover, speakers have intuitions that some poets' meter sounds more
complex than others. Most Russian speakers agree that Pushkin's meter
sounds more elaborate than Nekrasov's, although both employ the same
absolute restrictions and deviate from the ideal iambic template just as
often. Such intuitions about complexity in meter remain largely
unexplained either by literary criticism or by generative approaches to
meter (Halle and Keyser 1971, Kiparsky 1975). I propose a theory that
measures this complexity and apply it to the omission of stress in Russian
iambic tetrameter. Following work in constraint-based theories of
metrics (Hayes and MacEachern 1998), I employ stochastic constraints (i.e.
constraints responsible for generating frequencies) in order to model
metrical preferences of XVIII-XIX century Russian poets. However, I go
beyond earlier proposals and demonstrate that metrical complexity can be
measured using three explicit parameters - the number and type of
constraints actively employed by the poet, and the number of ways a
hierarchy of poet's preferences can be achieved. I examine a large
statistical database of Russian iambic tetrameter (Taranovski 1953) and
formulate weighted constraints, generating hierarchies of metrical
preferences for 37 Russian poets at different stages of their lives.
Ideally, weak (W) and strong (S) positions in iambic meter correspond to
unstressed and stressed syllables; however, Russian poets often violate
the pattern by filling strong positions with unstressed syllables. For
example, in (1) the penultimate strong position is filled by an unstressed
syllable 'za' (stressed syllables are capitalized)

(1) shows four sites of potential stress omission. No poets in the database
omit stress on the last foot. However, they omit stress on non-final
feet; omission on the penultimate foot is the most favoured type.
Preferences for omission on first, first and third, second foot, etc.,
vary among poets. I organize attested omission types into frequency
hierarchies, yielding 11 patterns.
I derive these patterns using weighted constraints on well-formedness,
some of which aim to make salient edges of metrical constituents (Hayes
and MacEachern 1998) and others to govern the number of stresses in each
constituent. The frequency of a line type depends on the weight of the
appropriate constraint in a poets grammar. Not all constraints are
weighted - some are inviolable, such as the requirement that the end of
the line be salient.
Looking across poets and times, two types of preference-patterns emerge -
SIMPLE patterns (like Nekrasov's) are generated by four constraints,
COMPLEX patterns (like Pushkin's) are generated by five. Simple patterns
can be derived by weighting constraints in several distinct ways. Complex
patterns can be derived by just one solution in constraint ordering,
making it harder for a poet to arrive at that result. Both complex and
simple patterns actively utilize constraints requiring the saliency of
edges, but only complex patterns make use of the constraint Symmetry,
requiring paired half-lines to have identical rhythmical structure.
The model shows that constraints can be helpful in linguistic research
not only in generating desired outputs, but also in measuring speakers
intuitions about verse. From the point of view of metrics, this approach
objectively measures metrical complexity instead of intuitively stating
that the meter of some poet 'sounds more elaborate'.
