19th century, he used contemporary classical music as inspiration, in particular a popular Beethoven septet of the period, as well as a theme strongly reminiscent of the finale of Beethoven's Emperor Concerto. For control over the sound, the music was recorded in six hours by a group of up to 18 musicians and was then fed into tiny earpieces of the screen musicians, who mimed playing the instruments. The actresses whose characters played the piano, Lucy Briers (Mary) and Emilia Fox (Georgiana), were already accomplished pianists and were given the opportunity to practice weeks ahead of filming. Among the songs and movements that were played in the serial were Handel's "Air con Variazioni" from Suite No. 5 in E Major HWV 430 and "Slumber, Dear Maid" from his opera Xerxes (in 1813 these works by Handel would have been considered quite old-fashioned, adding to the perception that Mary's tastes are a bit out of fashion), Mozart's "Rondo alla turca", "Voi che sapete" and other music from his operas The Marriage of Figaro and Don Giovanni, Beethoven's Andante favori, the second movement from Muzio Clementi's Sonatina No.4 and the traditional folk song "The Barley Mow". A soundtrack with Davis's themes was released on CD in 1995. The text of Mozart's "Voi, che sapete"(sung in an English translation) is a particularly meaningful choice: the original Italian is a love song, including the words "You, who know what love is, tell me, is that what I feel in my heart?" Lizzie sings this, and soon after, she graciously "saves" Georgiana from embarrassment at the mention of Wickham, and Darcy further realizes her good heart. This musical theme is soon echoed, after that episode, as Darcy walks along the hall; tell me, is love what I feel in my heart? Many scenes in the book were set at dances or balls. Jane Gibson based her choreography on The Apted Book of Country Dances (1966) by W.S. Porter, which had several late-18th-century dances by Charles and Samuel Thompson such as "The Shrewsbury Lasses", "A Trip to Highgate" and "Mr. Beveridge's Maggot". Although these dances gave the story an impression of authenticity, they were anachronistic, being out of fashion by the time of the story. Some fifteen dances were choreographed and rehearsed before filming. Polly Maberly and Julia Sawalha, the dance-mad Kitty and Lydia, had three days to learn the dances. Three days were allotted for
