Ludwig van Beethoven’s Missa solemnis (Solemn Mass in D major, op. 123) is one of the most majestic and demanding masterpieces in Western music, a deeply spiritual work that transcends the boundaries of liturgical music, transforming into a personal confession, a prayer, and a hymn to peace.

Beethoven began composing this work in 1819 to mark the appointment of his patron, student, and friend, Archduke Rudolf of Austria, as the Archbishop of Olomouc. However, the scale and ambition of the piece led to a four-year creative process, and it ultimately premiered in 1824 in St Petersburg.

Based on the text of the Catholic Holy Mass and structured in five sections—Kyrie, Gloria, Credo, Sanctus, and Agnus Dei—, Missa solemnis combines explosive drama, mystic innerness, and musical complexity unprecedented for its time, remaining one of the most taxing works in the choral and symphonic repertoire.

The work will be performed for the first time by the Greek National Opera in a stage version featuring the full artistic forces of the GNO (Orchestra, Chorus, Ballet).
