Navigation etc.

In this sonata (my longest and most complex organ piece to date), I used 5 Gregorian chants, associated with Easter:

  • In the first movement, the Easter hymns O Filii et Filiae and Salve Festa Dies.
  • At the end of the second movement the Communio for Easter Sunday Pascha Nostrum is interwoven with the main theme of the movement.
  • In the final movement, the Fanfare section cites the Easter Proclamation Exsultet. In the massive triple fugue that follows, the Easter Sequence Victimae Paschali Laudes is used as the third theme. At the end there's a short reference to O Filii et Filiae again. Since the text of this hymn encompasses the entirety of the Easter Gospel, it means that at this point, the sonata has come full circle.
