The term “Octoïchos” describes the system of the eight ecclesiastical modes that is used in Ecclesiastical Chant. The system is very complex and can be sometimes confusing for modern listeners. Beyond its music theoretical significance, the system of the eight modes was also frequently charged with symbolic meaning. One of these symbolic interpretations is a fascinating connection between the modes and the liturgy.

The liturgy is a story of salvation. The seven days of the week and the cyclical sequence of daily services, which culminate in the mass on Sunday, remind us of the seven days of the creation; however, the cycle also confronts us of the imperfection of earthly life. Our hopes are directed towards the eighth day, the day that is never reached within the weekly liturgical cycle. It is the first day of heaven, when all counting stops and timeless life begins. On the eighth day we rest with /at the same time that God rested. Hence, the perfect cycle of the eighth modes (the Octoïchal Cycle) is a symbol for the eschatological fullness of the history of salvation.

In spite of more than 1000 years of history, the number of modes never changed; we neither find less than eight modes nor do we find more. The reason for this is a theological one: The number eight symbolizes perfection. It symbolizes the entry into eternity, leading the weekly liturgical cycle to its ultimate end: the eternal Day of God.

This symbolism could be viewed as a secondary, theologically motivated interpretation of a musical phenomenon. But it is more than that. For the Syriac Church, on which the talk will focus, this symbolism describes an important aspect of its musical and liturgical identity.
