The chant book by Franciscan Pavao Vučković Junior, dated 1768, is kept today in the Archive of the Franciscan monastery in Sinj. Pavao Vučković Junior copied this manuscript in the church of San Francesco Grande in Padova. Later, this chant manuscript was corrected by the local maestro di cappella Giannantonio Banner. The manuscript consists of twelve cycles of the mass ordinarium, but there is also one proprium and an unfinished Magnificat (which is identical to the one writt en in the so-called 'Kantual B' by Petar Knežević). The chants are notated with black square mensural notation in the style of cantus fractus. Cantus fractus or »l'altro gregoriano« is a style notated with mensural and rhythmical proportional elements which was present from the 14th century until the 19th century in Italy, but this shows that it was also present in Croatia. The chant book of friar Pavao Vučković Junior was based on an Italian source, so the repertoire and the notation are similar to the Italian cantorie. Italian cantorie are specific because of the liturgical genres they contain: cycles of the mass ordinarium, as well as chants of the mass proprium, and isolated chants of Gloria and Credo. That means that this chant book of friar Pavao Vučković Junior corresponds with those of Italian contemporaries. Apart from being the corrector of the manuscript Giannantonio Banner was also a composer, and two of his masses are writt en down in this chant book. Except for those two masses, other masses were writt en by anonymous authors - actually they are probably part of the standard Franciscan repertoire. The masses are writt en for a one-part unison choir with the accompaniment of basso continuo. The mass proprium is writt en for the feast of the Assumption of Mary. That feast is especially celebrated in Sinj, which could mean that Vučković chose those chants on purpose. Also, the Magnificat, which can be found in other manuscripts from Sinj, could also imply that the manuscript was writt en specifically for use in the Franciscan monastery in Sinj. The chants resemble Gregorian chants but they also contain baroque rhythms and certain kinds of motivic work which provide a link between the beginnings of the parts of the mass. The research brings some preliminary insights into the life and work of two musicians mentioned in this chant book - scriptor friar Pavao Vučković Junior, and composer and corrector of the manuscript Giannantonio Banner. Not much is known about these two musicians. The majority of the information about Pavao Vučković Junior can be found in church books of the Franciscan monastery in Sinj. Information on Giannantonio Banner is scarce, but fortunately, besides his theoretical work Compendio musico, there are several music works which are preserved mostly in Italian and Croatian archives. This chant book is an example of a writt en «transfer" of the Italian Franciscan music culture to the Croatian hinterland, and Sinj. It proves that cantus fractus was a style which was widespread in Croatia. It also depicts the musical skill of the scriptor and musician friar Pavao Vučković Junior. Further work should focus on comparative analysis with Italian and other Croatian sources, which could lead to new insights into the handover of the Franciscan repertoire. [ABSTRACT FROM AUTHOR]
