Work by Leonin based on the Christmas Gradual. Perotin would later make his own version and embellish it.
Leonin's version of the Viderunt Omnes is composed in organum duplum. The chant is held in the tenor voice and moves slowly while the organal voice has a melismatic line. Rhythmic modes can be easily heard in this organum. The combinations of longs and shorts give a compound meter feel. (3 = trinity) Polyphonic music during this time was rather simple and still had sections of chant in unison.
Viderunt omnes fines terrae
salutare Dei nostri.
Jubilate Deo, omnis terra.
Notum fecit Dominus salutare suum;
ante conspectum gentium
revelavit justitiam suam.
All the ends of the earth have seen
the salvation of our God.
Rejoice in the Lord, all Lands.
The Lord has made known his salvation;
in the sight of the heathen
he has revealed his righteousness.
