Lobgesang (Hymn of Praise), Op. 52 (MWV A 18), 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. History It was composed in 1840, along with the less-known Festgesang "Gutenberg Cantata", to celebrate the 400th anniversary of the invention of Johannes Gutenberg's movable type printing system. In 1842 Mendelssohn had published his Scottish Symphony as "Symphony No. 3", however a "Symphony No. 2" had never been published during Mendelssohn's lifetime. Possibly the composer's intention was to spare this number for his earlier Italian Symphony, which he premiered in 1833, but afterwards withheld for a revision that was never completed. The Italian Symphony was published posthumously as "Symphony No. 4". Decades after Mendelssohn's death, the editors of the old Mendelssohn complete edition entered Lobgesang as "No. 2" in the sequence of this symphonies for editorial reasons. However, there is no indication that this represented the composer's intentions. The new Mendelssohn-Werkverzeichnis (MWV), published in 2009 by the Saxonian Academy of Sciences and Humanities, no longer lists Lobgesang among the symphonies, but rather among the sacred vocal works. Structure Structurally, it consists of three purely orchestral movements followed by 10 movements for chorus and/or soloists and orchestra, and lasts approximately 65–70 minutes in total. The English titles of the movements are: Sinfonia: Maestoso con moto - Allegro Allegretto un poco agitato Adagio religioso All men, all things, all that have life and breath (chorus) Let everything that has breath praise the Lord (soprano and semi-chorus) Sing ye Praise (tenor recitative and aria) All ye that cried unto the Lord (chorus) I waited for the Lord (soprano duet and chorus) The sorrows of Death (tenor Aria) The Night is Departing (chorus) Let all men praise the Lord (chorale, "Nun danket alle Gott") My song shall be always Thy Mercy (soprano and tenor duet) Ye nations, offer to the Lord (chorus) The now-standard harmonisation of "Nun danket alle Gott" by Martin Rinkart (1636) was devised by Felix Mendelssohn in 1840 when he adopted the hymn, sung in the now-standard key of F major and with its original German lyrics
