Document 4: Franz Liszt Academy of Music: The Liszt Ferenc Academy of Music (Hungarian: "Liszt Ferenc Zeneművészeti Egyetem" , often abbreviated as "Zeneakadémia", "Music Academy") is a concert hall and music conservatory in Budapest, Hungary, founded on November 14, 1875. It is home to the Liszt Collection, which features several valuable books and manuscripts donated by Franz Liszt upon his death, and the AVISO studio, a collaboration between the governments of Hungary and Japan to provide sound recording equipment and training for students. The Liszt Ferenc Academy of Music was founded by Franz Liszt himself (though named after its founder only in 1925, approx. 50 years after it was relocated to its current location at the heart of Budapest). Between 1877-1879 the Academy moved into its present building, a masterpiece of art Neo-Renaissance architecture.
Document 5: Hungarian Rhapsody No. 5: Hungarian Rhapsody No. 5, S.244/5, in E minor, is the fifth in a set of 19 Hungarian Rhapsodies by composer Franz Liszt. It is marked "Lento, con duolo". The piece was given the nickname "Héroïde-élégiaque" by the composer himself. It is very different from his other Hungarian Rhapsodies, as it does not follow the "intro" - "lassan" - "friska" structure and is perhaps the darkest and most melancholic of the set. It was later arranged for orchestra.

Document 10: O lieb, so lang du lieben kannst: O lieb, so lang du lieben kannst is a poem written by Ferdinand Freiligrath, a 19th-century German writer. In 1847, Hungarian composer Franz Liszt set the poem to music (soprano voice and piano), and eventually adapted it into his famous Liebesträume No. 3. The work is one of Liszt's most famous and poignant. "Liebesträume" in German means "Dreams of Love".
Document 11: Héroïde funèbre (Liszt): Héroïde funèbre , S. 102, is a symphonic poem written by Franz Liszt in 1850 and published in 1857 as No. 8. The work originated as the first movement of a planned "Revolutionary Symphony" inspired by the July Revolution. Liszt pays homage in this programmatic symphonic poem to the soldiers and men that died fighting in revolutionary efforts. The composition of this piece was started in 1830 as a brief sketch for a full symphony, but was dropped by Liszt in the continuing of other works. However, in 1848, there was an uprising in Liszt's home country of Hungary. One of Liszt's friends was killed during this revolution, which caused Liszt to revisit his now 20 year old sketch of the Revolutionary Symphony, shortening it and forming the first movement into the commemorative Héroïde funèbre. Liszt said of the program, "In these successive wars and carnages, sinister sports, whatever be the colours of the flags which rise proudly and boldly against each other, on both sides they float soaked with heroic blood and inexhaustible tears. It is for Art to throw her ennobling veil over the tomb of the brave, to encircle with her golden halo the dead and dying, that they may be the envy of the living."
Document 12: Ktož jsú boží bojovníci: The song was sung with such intensity during the Hussite Wars, that it instilled fear throughout the enemy army, making it a weapon in itself. One of the Imperial Crusades is believed to have fled the battlefield before the battle itself, just by hearing the Hussites singing proudly their hymn. The hymn would be led by a Hussite priest, who would be carrying a ceremonial axe. At the start of the 1433 war between the Polish and the Teutonic Knights of Prussia, the Hussites signed an alliance against the Germans in July 1433. In the course of the war, they marched all the way to the Baltic sea at the town of Danzig. The Prussian 19th-century historian, Heinrich von Treitschke, makes a clearly indignant reference to the Hussite taking of land near the Baltic Sea and to "Kdož jsou Boží bojovníci" with these words: "greeted the sea with a wild Czech song about God's warriors and filled their water bottles with brine in token that the Baltic once more obeyed the Slavs."
Document 13: Sardanapale: Sardanapale (French for "Sardanapalus"), S.687, is an unfinished opera by Franz Liszt based loosely on the 1821 verse play "Sardanapalus" by Lord Byron.
Document 14: Hamlet (Liszt): Hamlet, S.104, is a symphonic poem by Franz Liszt, written in 1858 and published as No. 10. It was not performed until 2 July 1876. Like all but one of Liszt's 13 symphonic poems, "Hamlet" was written while Liszt was working in Weimar and is dedicated to Carolyne zu Sayn-Wittgenstein. After viewing Bogumil Dawison play Hamlet in Weimar (1856), Liszt wrote: "He does not make him into an indecisive dreamer who collapses under the power of his mission, as he is regarded since Goethe's theory in "Wilhelm Meister", but much more as a gifted, enterprising prince with important political views who is waiting for the right moment to complete his work of revenge and come to the aim of his ambition, that is, to be crowned king in place of his uncle. This goal can naturally not be reached in twenty-four hours and the clever anticipation which Shakespeare has put into the role of Hamlet and the negotiations with England which come clearly to the light of day at the end of the drama according to my view justify Dawson's interpretation, which Herr von Goethe and the aesthetes should not take too badly. Regarding Ophelia, Liszt wrote: "She is loved by Hamlet, but Hamlet, like every exceptional person, imperiously demands the wine of life and will not content himself with the buttermilk. He wishes to be understood by her without the obligation of explaining himself to her. She collapses under her mission, because she is incapable of loving him in the way that he must be loved, and her madness is only the decrescendo of her feeling, whose lack of sureness has not allowed her to remain on the level of Hamlet." Liszt's "Hamlet" is meant as a psychological study of the title character; only two brief references are made to Ophelia, both marked as "to be played as quietly as possible and sound like a shadowy picture."
