While playing expressively, cellists tend to produce postural movements, which seem to be part of their musical discourse. This article actually highlights the existence of a metric embodiment, i.e. a natural encoding of the score metric structure through specific periodicities of the musicians' postural movements. By the means of constrained postu-ral conditions, we assess the degradation of the metric coupling between postural and bowing gestures among several cellists. Results reveal that bowing displacements should be in coherence with their postural behavior in order to ensure a correct encoding of the metric hierarchy.
