Proměny českého chorálu v 16. století – pokus o klasifikaci redakcí českého chorálu 16. století na příkladu aleluja ke svátku Nanebevzetí Panny Marie

This study is an attempt at a preliminary classification of Czech plainchant from the sixteenth century based on differentiation among different selections and adaptations thereof that substantially changed the chants over the course of time. This classification and the transformations effected in various adaptations are illustrated using the example of the Alleluia for the feast of the Assumption of the Virgin Mary. In the second half of the article the author attempts to sketch an interpretation of the observed changes in text and melody in relation to the context of liturgical singing in the Czech Utraquist church during the sixteenth century.
