Kubelík, Otmar Suitner, Libor Pešek, Zdeněk Mácal, Václav Neumann, Witold Rowicki, Jiří Bělohlávek, and Neeme Järvi. Adolf Čech premiered more of Dvořák's symphonies than anyone else. He conducted the first performances of Nos. 2, 5 and 6; the composer premiered Nos. 7 and 8; Bedřich Smetana led Nos. 3 and 4; Anton Seidl conducted No. 9; and Milan Sachs premiered No. 1. Symphonic poems Franz Liszt invented the symphonic poem, never employed by more conservative Romantic composers such as Brahms. Dvořák wrote five symphonic poems, all in 1896–1897 with sequential opus numbers: The Water Goblin, Op. 107; The Noon Witch, Op. 108; The Golden Spinning Wheel, Op. 109; The Wild Dove, Op. 110; and A Hero's Song, Op. 111. The first four of poems are based upon ballads from the collection Kytice by the Czech folklorist Karel Jaromír Erben. A Hero's Song is based on a program of Dvořák's devising and is believed to be autobiographical. Choral works To Dvořák's main choral works belong his setting of Stabat Mater (the longest extant setting of that text), his Requiem, his setting of the Te Deum and his Mass in D major. The Stabat Mater, Op. 58, is an extensive (c. 90 minutes) vocal-instrumental sacred work for soli (soprano, alto, tenor and bass), choir and orchestra based on the text of an old church hymn with the same name. The inspiration for creating this piece was the death of the composer's daughter, Josefa. Antonín Dvořák composed his Requiem in 1890, at the beginning of the peak period of his career. Dvořák was deeply religious, and this work reflects his faith and spirituality. The premiere took place on 9 October 1891 in Birmingham, conducted by Dvořák himself, and was "very successful". It had an outstanding success in Boston 30 November 1892: "the composer was frequently applauded between numbers and given a most enthusiastic ovation at the end.". In Vienna it was greeted, belatedly, in 1901: "The Vienna performance in March 1901 was a triumph of Dvořák's music, as if the Viennese public wished thereby to make up for their earlier, sometimes cool reception of his works." The Te Deum, Op. 103, is a cantata for soprano and baritone solo, choir and orchestra to the Latin text of the famous hymn Te Deum (God, we laud You). It was composed in 1892 and dedicated to the 400th anniversary of the discovery of America. The
