Lobgesang, Op. 52, is an 11-movement "Symphony-Cantata on Words of the Holy Bible for Soloists, Choir and Orchestra" by Felix Mendelssohn. After the composer's death it was published as his Symphony No. 2 in B-flat major, a naming and a numbering that are not his. The required soloists are two sopranos and a tenor. The work lasts almost twice as long as any of Mendelssohn's purely instrumental symphonies.
Mendelssohn in 1846
A choral symphony is a musical composition for orchestra, choir, and sometimes solo vocalists that, in its internal workings and overall musical architecture, adheres broadly to symphonic musical form. The term "choral symphony" in this context was coined by Hector Berlioz when he described his Roméo et Juliette as such in his five-paragraph introduction to that work. The direct antecedent for the choral symphony is Ludwig van Beethoven's Ninth Symphony. Beethoven's Ninth incorporates part of the ode An die Freude, a poem by Friedrich Schiller, with text sung by soloists and chorus in the last movement. It is the first example of a major composer's use of the human voice on the same level as instruments in a symphony.
Hector Berlioz was the first to use the term "choral symphony" for a musical composition—his Roméo et Juliette.
Ludwig van Beethoven redefined the symphony genre by introducing words and voices in his Ninth Symphony.
Krzysztof Penderecki wrote his Seventh Symphony to celebrate the third millennium of the city of Jerusalem.
Walt Whitman's use of free verse became appreciated by composers seeking a more fluid approach to setting text.
