Roy Dotrice, OBE (born 26 May 1923) is a British actor known for his Tony Award-winning Broadway performance in the revival of "A Moon for the Misbegotten".
 Film audiences know him best for his role as Leopold Mozart in the Oscar-winning film "Amadeus".
 He is also known for narrating the audio book versions of the "A Song of Ice and Fire" series.
The piece of music once known as Wolfgang Amadeus Mozart's Symphony No. 2 in B♭ major, KV 17, is now considered to be not by him, but by possibly his father, Leopold Mozart.
 This symphony has been given the number Anhang C 11.02 in the sixth edition of Ludwig Ritter von Köchel's catalog of Mozart's music.
 , and is now also catalogued as Eisen B♭ 6 in Cliff Eisen's catalog of Leopold Mozart's symphonies.
The Mozart family grand tour was a journey through western Europe, undertaken by Leopold Mozart, his wife Anna Maria, and their musically gifted children Maria Anna (Nannerl) and Wolfgang Amadeus from 1763 to 1766.
 At the start of the tour the children were aged eleven and seven respectively.
 Their extraordinary skills had been demonstrated during a visit to Vienna in 1762, when they had played before the Empress Maria Theresa at the Imperial Court.
 Sensing the social and pecuniary opportunities that might accrue from a prolonged trip embracing the capitals and main cultural centres of Europe, Leopold obtained an extended leave of absence from his post as deputy Kapellmeister to the Prince-Archbishop of Salzburg.
 Throughout the subsequent tour, the children's "Wunderkind" status was confirmed as their precocious performances consistently amazed and gratified their audiences.
Josef Mysliveček (9 March 1737 – 4 February 1781) was a Czech composer who contributed to the formation of late eighteenth-century classicism in music.
 Mysliveček provided his younger friend Wolfgang Amadeus Mozart with significant compositional models in the genres of symphony, Italian serious opera, and violin concerto; both Wolfgang and his father Leopold Mozart considered him an intimate friend from the time of their first meetings in Bologna in 1770 until he betrayed their trust over the promise of an operatic commission for Wolfgang to be arranged with the management of the Teatro San Carlo in Naples.
 He was close to the Mozart family, and there are frequent references to him in the Mozart correspondence.
Tales from the Crypt is a 1972 British horror film, directed by Freddie Francis.
 It is an anthology film consisting of five separate segments, based on stories from EC Comics.
 Only two of the stories, however, are actually from EC's "Tales from the Crypt".
 The reason for this, according to "Creepy" founding editor Russ Jones, is that producer Milton Subotsky did not own a run of the original EC comic book but instead adapted the movie from the two paperback reprints given to him by Jones.
 The movie was one of many Amicus horror anthologies made during the 1970s and features an all star cast, including Joan Collins, Peter Cushing, Richard Greene, and Roy Dotrice, with Ralph Richardson as the Crypt Keeper.
Bölzlschiessen was a form of domestic recreation that involved shooting darts at decorated targets with an air gun.
 It is remembered as an activity of Leopold Mozart, his family, and their friends.
 The most famous participant was Leopold's son Wolfgang Amadeus Mozart, who began playing at the age of ten.
This is a list of symphonies by the classical composer Wolfgang Amadeus Mozart.
 Symphonies No.
 2 (attributed to Leopold Mozart) and 3 (written by Carl Friedrich Abel) are spurious.
 Spurious symphonies can be found at Mozart symphonies of spurious or doubtful authenticity.
 Symphonies that are suspected to be not Mozart's, but have not been proven to be the work of another composer, are in this list.
 Mozart's "37th symphony" is actually Michael Haydn's 25th symphony; Mozart only added a 20-bar slow introduction to it.
Pietro Antonio Lorenzoni (1721–1782) was an Italian painter who is believed to have painted several portraits of Wolfgang Amadeus Mozart and his family: "The Boy Mozart" (1763), his sister Maria Anna Mozart in "Nannerl as a Child" (1763) and a portrait of their father Leopold Mozart (c. 1765).
 He arrived in Salzburg, Austria in the 1740s and first wanted to paint Wolfgang and Nannerl.
 His protégé, Johann Nepomuk della Croce, painted a Mozart family portrait in 1780.
Mozart's birthplace (German: Mozarts Geburtshaus or Hagenauerhaus ) was the birthplace of Wolfgang Amadeus Mozart at No. 9 Getreidegasse in Salzburg, Austria.
 The Mozart family resided on the third floor from 1747 to 1773; Mozart himself was born here on 27 January 1756.
 He was the seventh child of Leopold Mozart who was a musician of the Salzburg Royal Chamber.
Mozart 252 is a 2008 album by Michael Nyman (his 58th release) with the Michael Nyman Band, Hilary Summers, and Andrew Slater, celebrating the 250th anniversary of Wolfgang Amadeus Mozart's birth.
 Although "Revisiting the Don," one of only two newly written works on the album, was commissioned and performed in 2006, the album's title is a joke on its lateness as an album, released 252 years after Mozart's birth ("it seemed more appropriate to miss the beat by two years").
 The album also includes "In Re Don Giovanni," Nyman's first composition for the band, which is based on the first fifteen bars of "Madamina, il catalogo è questo" from "Don Giovanni", six selections from Peter Greenaway's film, "Drowning by Numbers", in which he was instructed to base the music on the slow movement of Mozart's Sinfonia Concertante K. 364, and two duets and an aria from Nyman's television opera, "Letters, Riddles and Writs", in this recording featuring bass Andrew Slater as Leopold Mozart and contralto Hilary Summers as Wolfgang.
