The Sluzar Music Score is a collection of over 1,600 handwritten, copied and printed sheet music items and musical scores, and it contains more than 2,500 individual songs. It contains a unique variety of musical genres – from folk songs to opera and operetta scores, and from classical to liturgical and spiritual songs. Most of the pieces are arranged for choral performance; however, many solos, duets, quartets, and even instrumental arrangements are included as well.

The collection spans nearly a century in its compositions and publications, from the late 1800s to the end of the 20th century. Its songs reflect the incredibly rich historical legacy of the Ukrainian people and chronicle events from Cossack and chumak times all the way to the World Wars of the 1900s. The collection also strongly reflects the customs and traditions of the Ukrainian people through its assortment of folk songs – from hahilky and Kupalo songs to koliadky and shchedrivky.
