Résumé

We are questioning the classical metrical approach of the rhythmic phenomena incounting-out and nursery rhymes. According to the generative metrical model, aphonological structure is constructed by concatenation of symbols on a deepphonological level. Further rules driven transformations apply till the surfacingphonetics output. The problem appears when we consider the relationship betweenmetrics and verses. In this model the rhythmical alignment is strict and adisplacement of the rhythm relative to the textual structure (the verse) is not possible- prosodic and textual frontiers (rhymes and assonance) are coinciding.The classical approach will consider strong and weak metrical positions as functionally equivalents. Conflicts are resolved by adding empty positions or extra-metrical, not surfacing beats, which is a very questionable way to patch the theory when it fails to account of the data in a natural way. In addition it complicates thelearnability of the structures from the surface data.A good example for the problems inherent in the classical approach are the 3 beats counting-out rhymes, like in the French Am stram gram or the Italian An gbin go. Onthe underlying level they are represented as a malformed 4-beat structure.There is another approach derived from the musical practice. Consider a conductorof an orchestra, counting the beats. He will count only the strong positions: X X X X,but never Xo Xo Xo Xo. Thatʼs because in musical representation weak and strongbeats are not doing sense without the whole rhythm. The cognitive status of therhythm is different here. It is not dependent of the symbols (or constituents), and thelevel of representation is the one of an autonomous rhythmical curve, a kind of waveor oscillator.According to the dynamic account proposed by Goldsmith and Larson (1992), thenLaks (1997) the rhythm level is autonomous and is the product of such phenomenalike direction, limits and impulsion resolution. Simple connectionist-like networks areused to model the rhythmical curve. Dynamic Computational Nets (DCN), are alsoused for modeling the syllable and the stress domain as they provide a natural andlearnable alternative to the constituents based metrics.We are presenting the first results of a DCN network model of the metrics ofcounting-out rhymes in French, Italian, Russian and Bulgarian. Emphasis is put onthe learning of the network parameters (leftward, rightward connections, initial and final activation/inhibition) for different rhythmic types.
