Hundreds of fragmentary notated manuscripts have survived in the territory of Slovakia. Medieval fragments from the eleventh to the fifteenth centuries are deposited in several Slovak archives, libraries, and museums. One of the archives that house a large number of notated fragments is the State Archive in Trenčín. During our music historical field research in this archive, we processed twenty-two notated medieval manuscripts in total. We analysed eleven fragments of antiphonaries, eight graduals, one missal, one breviary, and one fragment whose contents we did not manage to identify because it was severely damaged. Sixteen fragments are notated in Bohemian notation, which makes the State Archive in Trenčín the archive with the largest number of medieval fragments with this system of notation. This study aims for an in depth musical and liturgical analysis of the medieval office repertoire recorded in the fragments, identified in an interdisciplinary codicological palaeographic and music-palaeographic research to have belonged to a single liturgical codex which has unfortunately not survived in its entirety.
