Troparion A troparion (, pluraltroparia, τροπάρια; Church Slavonic:tropar) in Byzantine music and in the religious music of Eastern Orthodoxy 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.
