Diptyque

Historical context

Messiaen composed the Diptyque for organ in 1929–30, while he was still a student at the Paris Conservatoire, and dedicated it to his two teachers there, Paul Dukas and Marcel Dupré. He gave the first performance himself on 30 March 1930 at the Église de la Sainte-Trinité in Paris — the church where, the following year, he would become titular organist and remain for sixty-one years.

The work’s full subtitle, Essai sur la vie terrestre et l’éternité bienheureuse (essay on earthly life and blessed eternity), explains its two-panel “diptych” form: a turbulent, dissonant first part depicting earthly life with its useless agitations, which breaks off into a slow, luminous Paradis. That serene conclusion had a remarkable afterlife. As a prisoner of war at Stalag VIII-A in 1940, Messiaen reworked it from memory for violin and piano, transposed and greatly slowed, as the closing Louange à l’Immortalité de Jésus of his Quatuor pour la fin du temps.
