By tradition, Byzantine dance is linked with both classical antiquity and today’s folk dances of the southern Balkans. Turkish influence on the latter seems limited primarily to musical instruments and melody but does not appear to include rhythm. In antiquity, and in Byzantine times, the simple rhythmic foot was divided into arsis and thesis, the ‘up’ and ‘down’ of a step, and the ratio of their lengths determined the rhythmic genus, 1:1 dactylic, 2:1 iambic, 3:2 paeonic and 4:3 epitrite. This (...) implies measures of 2, 3, 4, 5 or 7 units and certain multiples. In addition, there were also composite rhythmic feet which combined simple feet of different genera. In early Byzantium, for example, measures of 11 and probably of 9 units were used. These seem to correspond to the forms 3+3+2+3, 2+3+2+2+2 and 2+2+3+2. This would suggest that the asymmetric rhythms of Greek, Bulgarian and Macedonian folk dances derive from ancient and Byzantine predecessors. (shrink)
