In a previous post I shared some examples of Lenten Tracts in a simple organum setting by Alastair J. Tocher, director of the Schola Gregoriana Malvernensis. Here are some further resources for Palm Sunday and Easter:
Palm Sunday: The Gradual (Gregorian, with simplified psalm tone verse).
Palm Sunday: The Tract (Gregorian, with alternating psalm tone and organum verses).
Easter Sunday: Gregorian/Polyphonic Gradual. Alastair has prepared a new edition of the Gradual - Haec dies - for Easter Sunday in which the Respond (the initial portion) is sung in Gregorian chant but with the Verse sung in a simple four-part setting by Cesare de Zacharia (circa.1594).
The edition is available free for liturgical use.
Easter Sunday: Gregorian/Polyphonic Alleluia. He has also prepared a new edition of the Alleluia - Pascha nostrum - for Easter Sunday in which the initial Alleluia is sung in Gregorian chant, the verse is sung to a simple psalm tone (VII), and the final Alleluia is sung in a simple four-part setting by Giuseppe Pitoni (1657-1743).
The edition is free for liturgical use.
Many thanks to Alastair for sharing these, and best wishes to all of you who are currently preparing music for the Holy Week and Easter liturgies.
