Czech Christmas Mass
Czech Christmas Mass (Czech: Česká mše vánoční; Latin: Missa solemnis Festis Nativitatis D. J. Ch. accommodata in linguam bohemicam musikamque redacta – que redacta per Jac. Joa. Ryba) is a classic pastoral mass written by the Czech composer Jakub Jan Ryba in 1796. Because of its opening words, it is also known as Hail, Master! or Hey, Master! (in Czech: Hej, mistře!). Czech Christmas Mass was composed in a frame of traditional Latin mass (with parts Kyrie, Gloria etc.), the story is based on Christian theme of the birth of Jesus of Nazareth. Despite this, the work has a rather pastoral character with emphasis on a Czech description of the nativity in a Czech setting. During the centuries, the composition became the most popular Christmas mass in Czech countries and one of the musical symbols of Czech Christmas.
Background
Ryba composed his most famous work in 1796, a year after he managed to resolve a dispute over his teaching methods with the priest Kašpar Zachar. He wrote the music to his own Czech libretto; It was his only mass composed to the Czech text. Ryba did not record this mass in his list of compositions created from 1782 to 1798; he mentioned only "seven pastoral masses, one of them in the Czech language". The autograph manuscript was lost; today only the title page is preserved intact. Some parts of the composition were performed separately as pastorales and the text gradually adapted with changes in the Czech language. Though Ryba created more than 1,000 compositions, Czech Christmas Mass remains one of the few works performed regularly to date.
