Editing Duck Soup (1933 film) (section)

==Soundtrack==
Breaking with their usual pattern, neither Harpo's [[harp]] nor Chico's [[piano]] is used in the film, although Harpo briefly pretends to play harp on the strings of a piano.

The musical introduction to Groucho's character is similar to those in ''Animal Crackers'' and ''Horse Feathers'', but it did not become closely associated with him as did "[[Hooray for Captain Spaulding]]" from ''Animal Crackers''.

Zeppo, playing according to [[James Agee]] "a peerlessly cheesy improvement on the traditional straight man",<ref>{{cite book  | last = Adamson  | first = Joe  | title = Groucho, Harpo, Chico and Sometimes Zeppo: A Celebration of the Marx Brothers  | location= New York City| publisher=Simon and Schuster | year = 1973  | isbn = 0671470728 }}</ref> sings with the group, including soloing the first few lines of the first song, "When the Clock on the Wall Strikes 10". He also sings with the others in "Freedonia's Going to War", filling out the four-cornered symmetry as the Brothers sing and dance in pairs during the number.<ref name="Griffin">{{cite web  | last = Griffin  | first = Danel  | title = ''Duck Soup'' review  | work = Film as Art  | publisher = [[University of Alaska Southeast]]  | url = http://uashome.alaska.edu/~dfgriffin/website/ducksoup.htm  | archive-url = https://archive.today/20121203234711/http://uashome.alaska.edu/~dfgriffin/website/ducksoup.htm  | url-status = dead  | archive-date = 2012-12-03  | access-date = 2007-12-30  }}</ref>

===Original songs by Kalmar and Ruby===
The "Freedonia National Anthem" is used frequently throughout the film, both as vocal and instrumental; the entire song seems to consist of "Hail, Hail, Freedonia, land of the brave and free", contrasting with the final line of ''[[The Star-Spangled Banner]]''. The "Sylvania theme", which sounds vaguely like "[[Rule, Britannia!]]", is also used several times. "When The Clock On The Wall Strikes 10", the first musical number in the film, is part of the same scene as "Just Wait 'Til I Get Through With It",<ref name="filmsite"/> Groucho's song about the laws of his administration. "This Country's Going To War"<ref>TCM [https://www.tcm.com/tcmdb/title/73717/duck-soup Music]</ref> is the final musical ensemble in the film. Technically it is the only musical number in the Marx Brothers' films to feature all four of the brothers. However, in ''[[Monkey Business (1931 film)|Monkey Business]]'', Chico briefly bangs on the piano while the other three play saxophones while eluding their pursuers on an [[ocean liner]].

The introductory scene, showing ducks swimming in a kettle and quacking merrily, is scored with an instrumental medley of the aforementioned songs, and it is also the only scene in the film that has to do with ducks and soup.

===Non-original music===

Walt Disney filed a lawsuit against Paramount Pictures, for using the song without permission, resulting in Disney winning the financial damages in a settlement.
