The aim of the presentation is to introduce and interpret the custom of winter with ’goat’ mask among Ceangăi people in Bacău County, Romania. To make dance the goat is the part of the tradition in last day of Old Year, when little groups of lads (in the past) or young boys (at present) visit every opened house in the village, where they chant their best wishes to the family and play a dramatic-mimetic performance with vocal and instrumental accompaniment. The custom has more names, such as kecskezes, hejgetes, uralas (in Hungarian) in the Moldavian Ceangăi villages. I started a dance anthropological research in communities with Hungarian origin of Bacău County in 2012, where I have collected narrative texts about the changes of kecskezes custom in the 20th century; as well during fieldworks, I have been able to make photos and videos about the alive custom. The goat dance has a deep symbolic system in the traditional culture of Moldavian Ceangăi people, which is confirmed by a fact, namely the figure of goat and the music accompaniment appear in their wedding traditions too, besides this, it is comparable with more ethnics – firstly with the Romanian and Moldavian – rites. The kecskezes has a significant role in the life of communities, because after the rehearsals of young people during more weeks, the tradition reinforces the social connection between generations with the help of visitation to every family, moreover it can represent their local identity. In the presentation, I would like to introduce the practice of goat dance with the help of a case study of Magyarfalu village on the score of archive and collected material from the social and dance anthropological perspective. Beside the exemplification of interethnic connection of tradition, my aim is to interpret the symbol system and sociocultural function of kecskezes custom.
