Ludwigsburg Palace (German: "Residenzschloss Ludwigsburg" ) is a massive, Baroque palace complex located in Ludwigsburg, Germany, about 12 km from the Baden-Württemberg state capital of Stuttgart.
 The palace complex, nicknamed the "Versailles of Swabia" is one of the largest Baroque palaces in Germany, and one of its most prominent features is the enormous garden around the palace of the same style.
 Today, its sumptuous interiors contain various museums and tourist shops.
Baron Hans Guido von Bülow (January 8, 1830February 12, 1894) was a German conductor, virtuoso pianist, and composer of the Romantic era.
 One of the most famous conductors of the 19th century, his activity was critical for establishing the successes of several major composers of the time, especially Richard Wagner and Johannes Brahms.
 Alongside Carl Tausig, Bülow was perhaps the most prominent of the early students of Hungarian virtuoso pianist, conductor and composer Franz Liszt – therein performed the first public performance of Liszt's Sonata in B minor in 1857.
 He became acquainted with, fell in love and eventually married Liszt's daughter Cosima, who later left him for Wagner.
 Noted for his interpretation of the works of Ludwig van Beethoven, he was one of the earliest European musicians to tour the United States.
Antonio Palomba (20 December 1705 - 1769) was an Italian opera librettist, notary, poet, harpsichordist, and music educator.
 He also worked as a notary.
 Born in Naples, he became a teacher of the harpsichord at the Teatro della Pace in 1749.
 Most of his more than 50 opera libretti were comedic works written for composers of the Neapolitan school.
 He also wrote some works for performance in Florence, Bologna and abroad.
 He died in Naples in 1769; one of the victims of a fever epidemic in the city.
 Many of his libretti were set more than once to music, and composers continued to use his libretti up into the 1830s.
Franz Carl Adalbert Eberwein (10 November 1786 - 2 March 1868) was a German composer and violinist.
 He was born in Weimar, Germany and learned music under the consultation of his father.
 He was good friends with Johann Wolfgang von Goethe, and put music to many of his works, such as "Faust" and to "Proserpina".
 There is also at least one flute concerto, a "quatuor brillant" (string quartet with leading violin; opus 4, after 1805?)
 in A major, song cycles and cantatas (some but not all to words by Goethe; also a Trauercantate to words by Friedrich Wilhelm Riemer, Eberwein's opus 21 published in 1830.)
Monrepos (German: "Seeschloss Monrepos" ) () is a lakeside palace in Ludwigsburg, Germany.
 Although quite far from and almost separate from Favorite Palace and Ludwigsburg Palace, by way of pedestrian paths it is connected to the rest of the grounds.
 It is one of the two minor palaces on the estate, along with the main one.
 The smaller ones were used as Hunting lodges.
 Of all 3, this is the only one that is still owned by the royal family of Württemberg after their overthrow in 1918.
 Much of the privately owned land surrounding Monrepos is now part of a golf course, unlike the state owned part, which is made up of parks and museums.
Wilhelm von Lenz (born 20 May 1809 in Riga - died 7 January 1883 in Saint Petersburg) was a Baltic German Russian official and writer.
 Wilhelm von Lenz was a friend of many mid-century Romantic composers, including Franz Liszt, Frédéric Chopin and Hector Berlioz, Lenz's most important and influential work was an early biography of the German composer Ludwig van Beethoven, entitled "Beethoven et ses trois styles" (1855), written in response to the disparagement of Beethoven by Alexander Ulybyshev in his "Nouvelle biographie de Mozart" (1843).
 Lenz promoted the idea (already suggested by earlier figures such as François-Joseph Fétis) that Beethoven's musical style be divided into three characteristic periods.
 Lenz's periodisation, with minor changes, is still widely used today by musicologists in discussing Beethoven's compositions.
