The churches of the Rusyn ethnic group, which following the Union of Brest became Eastern Catholics developed a form of congregational singing known as Prostopinije; recently, many Rusyns in the United States and central Europe have rejoined the Eastern Orthodox church, but Prostopinije remains in use by both groups of Carpatho-Rusyn heritage, and has been adapted for use in both traditional and modern English.
There exist official English translations of the Missal and Breviary of the Dominican Rite, but not of the other distinctive monastic usages.
[649] All of the Eastern Orthodox and Byzantine Catholic churches share a common set of hymnals, which provide the basic text for the hymns.
The Octoechos contains the hymns sung in each of the eight tones, used throughout most of the year; the Triodion contains the special hymns and liturgical propers of Lent and Holy Week, the Pentecostarion, also known as the Flowery Triodion, contains the equivalent proper hymns for Pascha (Easter), Bright Week, and the period of time lasting through the liturgical season generally known as Eastertide in the West, including the feast of the Ascension, Pentecost and culminating on the first Sunday after Pentecost, All Saints Day (according to the Byzantine liturgical calendar.
Lastly, the Irmologion, not specifically translated into English but included in other volumes, such as some editions of the Octoechos and Pentecostarion, contains the Irmoi, a standard set of responsaries sung during the canons at Matins.
The principal hymnal of the Syriac Orthodox Church is the Beth Gazo ("Treasury"); proper hymns for various feasts are also found in the books of the liturgy, the Shi'mo, or Divine Office, and the Fanqitho, which replaces the Shi'mo in Great Lent, Holy Week, Pascha and during major feasts throughout the church year.
[653] In contrast, both the Armenian Rite and Ethiopian Rite make use of musical notation, which in the case of the Ethiopian church is ancient, dating back to the 6th century; however, these churches serve their liturgies exclusively in Classical Armenian and Ge'ez respectively, and consequently, very little of their hymnals or other service books have been translated into English.
[653] The Assyrian Church of the East, the Ancient Church of the East, the Chaldean Catholic Church and the Syro Malabar Catholic Church use the East Syriac Rite, which like the West Syriac Rite lacks a system of musical notation and is instead passed down through oral tradition; it makes use of the following hymnals: the "Turgama" (Interpretation), containing hymns sung by deacons during the liturgy (our Graduals and Sequences), the David (Dawidha = Psalter), "Khudhra" (= "cycle", containing antiphons, responsories, hymns, and collects for all Sundays), "Kash Kõl" (= "Collection of all"; the same chants for week-days), "Kdham u-Wathar" (= "Before and after"; certain prayers, psalms, and collects most often used, from the other books), "Gezza" ("Treasury", services for feast-days), Abu-Halim (the name of the compiler, containing collects for the end of the Nocturns on Sundays), "Bautha d'Ninwaie" (= "Prayer of the Ninevites", a collection of hymns ascribed to St. Ephraem, used in Lent).
The "Taksa d'Husaia" contains the office for Penance, the "Kthawa d'Burrakha" is the marriage service, the "Kahneita", the burial of clergy, the "Annidha" that of laymen.
Lastly the "Khamis" and "Warda" are further collections of hymns (see Badger, "The Nestorians and their Rituals", London, 1852, II, 16–25).
