Messe C-dur für 4 Solostimmen, Chor und Orchester, op. 86

Messe C-dur für 4 Solostimmen, Chor und Orchester, op. 86 is a choral mass by Ludwig van Beethoven, composed and first performed in 1807. Scored for four solo voices, mixed choir and orchestra, it combines Classical-era choral conventions with Beethoven's expanding harmonic and orchestral language and occupies a transitional place in his sacred output between his middle-period works and his later large-scale compositions.
