The Te Deum is sung in Latin below by the Schola Gregoriana Mediolanensis of Milan, Italy. Anyone wishing to learn to read mediaeval musical notation, which is easier than one might think, will find it instructive to watch this.
Below the Concordia Oakland Choristers sing the Te Deum in English translation:
Many Christians will be aware of metrical versions of this hymn, the best known of which is probably Holy God, We Praise Thy Name, a translation of the German Großer Gott wir loben dich, written around 1774 by Ignaz Franz for the Katholisches Gesangbuch.
In 1696 Nahum Tate and Nicholas Brady included a versification of the Te Deum for their "New Version" Psalter. Some years ago I adapted their three stanzas and added three of my own to complete the hymn: O God, we praise you, we confess that you alone are Lord. In whatever form it is sung, the Te Deum deserves to be better known and more widely used amongst English-speaking evangelical Christians.
