The Institute for Culture and Society (ICS) of the University of Navarra and the Music Chapel of the Cathedral of Pamplona have published the book Motetes anónimos de la Catedral de Pamplona. This is the second volume of the project 'Chantria Pampilonense' which, with its second publication, gathers a selection of 21 anonymous and unpublished motets of the file of Music of the Cathedral.

According to their authors, these short musical compositions were composed in the first half of the 17th century following the aesthetic postulates of the 16th century and constitute an unpublished musical heritage of unquestionable value. Five motets belong to the Advent-Christmas liturgical cycle and sixteen to the Lent-Easter cycle, constituting a "good and original sample of this important liturgical genre".

The books seek to rediscover the cultural past of the foral community and make it available to society. For Rafael Zafra, researcher of the ICS, these volumes allow "bringing to light the jewels of the relevant heritage that the Cathedral holds in order to make them alive", as well as allowing "the recovery of the mass genre, which has practically disappeared".

The edition of these motets, published by Ediciones Universidad de Navarra (EUNSA) and the German Edition Reichenberger publishing house , is accompanied by a CD with a recording of four of the most representative motets at position of the Music Chapel of the Cathedral of Pamplona.

The collection 'Chantria Pampilonense' is the result of a agreement between the ICS -the research center in Humanities and social sciences of the University of Navarra- and the Capilla de Música and has been edited by Aurelio Sagaseta, director of the Capilla de Música, and coordinated by Rafael Zafra. It is part of the project of research DeMusica, one of the lines of 'Creativity and Cultural Heritage' of the ICS.

In September 2018 the first volume of the collection, Obras de maestros italianos en la Catedral de Pamplona, was published. In autumn 2019 a third book will be published where a singular version of Wolfgang Amadeus Mozart's Requiem, adapted in the first half of the 19th century for its performance in the Pamplona Cathedral, will be recovered.
