Gabriel Fauré's Requiem in D minor, Op. 48, written in his prime, is one of his best-known works.

It was premiered on January 16, 1888, at the Church of the Madeleine. This Mass for the Dead is considered one of Fauré's masterpieces and one of the most beautiful requiems of the 19th century. The work, written in a highly personal style, contains several pieces that can be ranked among the most moving in Western choral music.

The Canticle of Jean Racine, Op. 11, is a vocal piece composed in 1865 by Gabriel Fauré, then aged 19. Written for choir (soprano, alto, tenor and bass) with piano or organ, this piece is in the key of D-flat major.

After an introduction played on the piano (or organ), the choir enters section by section. At the fortieth bar, after an instrumental bridge, a modulating central section enters in A-flat major (then B-flat minor), where the work reaches its highest expressive level. Through a slow and solemn return, the piece then evolves back to its initial character.

There is a version for choir, harmonium and string quintet (1866) and a version for choir and orchestra (1906).

Dedicated to César Franck, the score won first prize for composition at the graduation competition of the Niedermeyer School in Paris, where Fauré was a student.

The Symphony No. 3 in E-flat major, known as the Eroica, Op. 55, is one of Ludwig van Beethoven's most significant works. Composed between 1803 and 1804, it was publicly premiered on April 7, 1805, at the Theater an der Wien in Vienna.

Originally dedicated to Napoleon Bonaparte, the symphony had its dedication removed when he proclaimed himself emperor. Beethoven then dedicated it to the memory of "a great man," before officially dedicating it to his patron, Prince Lobkowitz.

With its unprecedented scope, expressive power, and heroic ideal, the Eroica marks a major break with classicism and heralds the advent of musical romanticism. Beethoven himself considered it one of his greatest symphonies.
