Strictly speaking, '''Byzantine Chant''' is the sacred [[chant]] of [[Christian]] Churches following the [[Orthodox]] rite. This tradition, encompassing the Greek-speaking world, developed in [[Eastern Roman Empire|Byzantium]] from the establishment of its capital, [[Constantinople]], in 330 until [[fall of Constantinople|its fall]] in 1453. It is undeniably of composite origin, drawing on the artistic and technical productions of the classical age, on [[Judaism|Jewish]] music, and inspired by the [[monophony|monophonic]] vocal music that evolved in the early Christian cities of Alexandria, Antioch and Ephesu]Ephesus. In the [[Orthodox Church]] today, many churches use Byzantine Chant as their primary musical tradition, including the Churches of [[Church of Constantinople|Constantinople]], [[Church of Alexandria|Alexandria]], [[Church of Antioch|Antioch]], [[Church of Jerusalem|Jerusalem]], [[Church of Romania|Romania]], [[Church of Serbia|Serbia]], [[Church of Greece|Greece]], and [[Church of Cyprus|Cyprus]].
