Much scholarly effort was devoted to the historical development of language in the nineteenth and the early twentieth centuries, and this was one of the fundamental research topics in linguistics. For several reasons, a similar phenomenon in music was not given much scope. One reason was the barrier of neumatic notation, which has been posing many challenges to this day. This paper is a probe into the development of the Byzantine liturgical musical tradition, which has been similar to that of language in many ways. As the object of our research, we chose a unique sticheron-automelon, O House of Ephratha/Οἴκος τού Ἐφραθά, whose development can be traced back to the eleventh century and reaches up to its current, living tradition. The aim of this paper is to introduce Byzantine hymnography and liturgy to the reader and lead him through the development of hymns with examples of selected musical sources. The analysis includes reconstructions of its earlier phases recorded in adiastematic neumatic notations.
