editions of the Octoechos and Pentecostarion, contains the Irmoi, a standard set of responsaries sung during the canons at Matins. All of these works aside from the Irmologion exist in English translations, in various forms, including anthologies. One of the oldest and most comprehensive is The Divine Prayers and Services of the Orthodox Church, compiled by Fr. Seraphim Nassar, which contains substantial excerpts from the Octoechos, the Menaion, the Triodion and the Pentecostarion. Oriental Orthodox hymnals Like the Byzantine Rite, the West Syriac Rite uses an eight mode system of chant similar to Byzantine Chant and Gregorian Chant, however, traditionally this was not notated, but rather, the melodies were passed down via oral tradition. 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. Of these, only the book of the Liturgy containing the Anaphoras in various forms and the Shi'mo, have been translated into English. The Coptic Rite also lacks a system of musical notation; its system of chant, Tasbeha, is somewhat less complex than West Syriac Chant; it is not based on eight modes, but rather a few sets of melodies for use on different occasions; it is passed down primarily as oral tradition, and certain portions of it, for example the chanting of the priests, rely on improvization based on the use of standard musical phrases. The Coptic Euchologion contains the hymns of the Divine Liturgy, whereas the books of the Annual Psalmody and the Khiak Psalmody contain the hymns of the divine office, the latter specifically for the season of Advent. There is also a book of offices for Holy Week, and various books containing special services such as funerals, marriages and ordinations, all of which have been translated into English. There also exist trilingual hymnals containing the Divine Liturgy of St. Basil set to Western notation. 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
