A troparion (Greek , plural: troparia, τροπάρια; Church Slavonic: тропа́рь, tropar′) in Byzantine music and in the religious music  of Eastern Orthodox Christianity is a short hymn of one stanza, or one of a series of stanzas. The word probably derives from a diminutive of the Greek tropos (“something repeated”, “manner”, “fashion”). The early troparion was also called sticheron (probably from stichos, “verse”); but currently the two terms are treated separately, with different melodies used for each.
