Description Schola Gregoriana Pragensis The Schola Gregoriana Pragensis is a choir from the Czech republic with primary focus on Gregorian chant and Bohemian plainchant. The choir formed in 1987 under the direction of David Eben and was restricted in its repertoire to only liturgical music for the first two years. Since the Velvet Revolution of 1989, the choir has extended its repertoire to include a variety of sacred music, with particular focus on Gregorian chant (monophonic Latin liturgical music) and early polyphony. The choir has won several awards, including the Choc du monde de le musique, 10 de Repertoire and Golden Harmony (Zlatá Harmonie). Since inception they have toured a variety of countries. Of particular importance is the choir's work in researching and performing Bohemian plainchant and early polyphony. The choir has between six and nine members with a repertoire of various sacred music. They have toured many countries, including Japan, Israel, Norway, Sweden, Italy, Spain, France, Germany, Austria, Belgium, the Netherlands, Luxembourg, Switzerland, Slovakia, Hungary and Poland. Their work in the interpretation of medieval music, with particular focus on Bohemian plainsong, is particularly significant with a focus on the symbolism of neumatic notation from the 10th and 11th centuries. Performances feature the original Bohemian plainchant tradition, including the earliest examples of polyphony. In addition they have performed music from 14th and 15th century and more modern compositions, including some written specifically for the group. They have produced numerous recordings under the Supraphon and other labels. The choir has participated in early music festivals, including the Festival Early Music at Utrecht in 2014.
