Future DevelopmentsVassil Stoin Project

Vasil Stoin is one of them and we propose to start with thedigitization of books, which are published in a result of Stoin’sproject in the 20s of XX century.

Vassil Stoin collections (books and unpublished records)are a valuable treasury of folk music heritage of BulgariaMuch of the notated songs published in these books havelong been forgotten and not persist in the musical practicesof Bulgarians. If they are published again and equippedwith sound examples, these songs can be sung again bythe modern and future fans of Bulgarian folk musicOnly single specimens from the collections are savedtoday, wasted by the time and usage. Many of these songsare threatened with extinctionTo our knowledge, Bulgaria is the only Balkan country thathas implemented such a comprehensive project forcollecting, deciphering and publishing folk music heritageStoin’s folk music collections cover almost all ethnographicregions in Bulgaria. They provide a unique music style ofthe Bulgarian Dialect AtlasThe launch of the Stoin’s project for collection andpublication of Bulgarian folk songs had taken place due tothe fact that this task was defined as a state priority by theMinistry of Education, funded by the Prime MinisterProfessor Alexander Tsankov in 1925 and by allsubsequent ministers until completion of the project

Our achievements are also a good base for internationalcollaboration in the field of authentic folk songs digitization.

One perspective is to take in mind the common features ofBalkan folklore (Romania, Serbia, Macedonia, Greece,Turkey), andother is to attract Cyrillic alphabet countries (Serbia,Macedonia, Bosnia and Herzegovina, Ukraine, Belarus,Russia).

An extended collection of digitized authentic folk songs fromseveral countries can generate many investigations aboutcommon roots of popular customs and culture of the people inthese countries.
