Movement 5: Benedictus
Movement 6: Agnus Dei
Many ideas for the music also came from Alexis: ‘the propers of the Mass … for Corpus Christi … contain magnificent Gregorian themes; perhaps you may be inspired by them?’ A later mention of the choral works with organ and brass of Gabrieli certainly gave Jongen the idea for the scoring, and it was perhaps Alexis’s vision that caused Jongen to write in a more contrapuntal vein than usual: a fugato with a regular countersubject for the ‘Pleni sunt caeli’ of the Sanctus, for instance; the main theme of the Benedictus announced in canon at the fifth; and the use of strict counterpoint in the vocal parts of the ‘Cum Sancto Spiritu’ (Gloria) and the ‘Et resurrexit’ (Credo). Alexis asked for the Kyrie to be without clamour and for the conclusion of the Gloria and the ‘Hosannas’ of the Sanctus to incorporate ‘superimposed voices … with organ, rising in a Babylonian crescendo, as Lekeu would have said’.
Sadly, Jongen’s personal circumstances prevented his composing anything between August 1944 and March 1945. His brother Alphonse, to whom he was particularly close, died after a difficult operation (the Mass is dedicated to the memory of Alphonse) and the news that his son, Jacques, had been arrested by the Gestapo left Jongen without the will to live. His memoirs become morbid, later describing how he felt like a rag, incapable of anything. The year 1944 he simply referred to as deathly, but the tone changes dramatically at the end of March 1945: ‘Jacques was in Buchenwald … Suddenly … we learnt that he was in Weimar and was soon to be liberated by the Americans—WHAT A RESURRECTION! It was then that I began to write the Mass.’
So it was that Jongen began to compose this complex work in a state of relief. Subtly cyclical, the links between the movements are not always easy to decipher: the organ chant of the opening Kyrie, for instance, is not only used in the vocal lines of the final Kyrie but is also developed at the ‘Qui tollis’ and ‘Qui sedes’ sections of the Gloria. It relates strongly to the ‘Cum Sancto Spiritu’ fugato (Gloria) and more subtly to many of the lines in the Benedictus and even the concluding section of the Agnus Dei. There are also links in the embedded contrapuntal vocal sections, which are often texturally rather than thematically related.
