psalmody

The deep root of psalmody is Greek psalmos, first tied to the twitch or pluck of strings. That noun comes from psallein, to pluck, especially a harp string, and then to sing with such accompaniment. Greek formed psalmodia for the singing of psalms. Music and text were joined from the start.

Jewish and Christian worship transformed the word's field. The biblical Psalms, translated into Greek in the Septuagint before the Common Era, gave psalmos a sacred corpus. By late antiquity, monasteries in places like Jerusalem and Constantinople used psalmodia for the patterned chanting of those texts. The act was no longer merely musical but liturgical.

Latin adopted psalmodia, and medieval church life spread it through Europe. English received psalmody in the 14th century from learned and ecclesiastical sources. By then it meant the singing or chanting of psalms, especially in public worship. It could also refer to the body of tunes and methods used for that practice.

Modern English keeps the churchward shape of the word. Psalmody can name congregational singing, chanted offices, or the musical tradition built around the Psalms. The ancient plucked string is mostly gone from view, but the sound remains implied. The word still hears music inside prayer.
