A collection of 16th century music hymnbooks preserved in the town of Sedlãany (located in Central Bohemia) allows a detailed study on the evolution of chant repertoire and liturgy in the Czech reformation. Three Sedlãany graduals were examined by means of statistical comparison with other sources regarding their texts, melodies, feasts and the liturgical functions of the chants. The case study on the Sedlãany graduals promotes a new method of research into the repertoire of liturgical manuscripts.
The Sedlčany Antiphonary CZ-S M-7 from the fifteenth or sixteenth century is one of only a few Utraquist sources for the divine office (canonical hours). The repertoire of the manuscript was examined with the help of the CANTUS Analysis Tool in order to find the feasts where the chants differ from most other liturgical traditions. Following an article devoted to Sedlãany graduals published in 2008, this new article presents another case study of the evolution of chant repertoire and liturgy in the Czech reformation.
