==Reorganisation== 
 There was an amount of material that dealt with the Tropak, which was not specifically about this piece of music by Tchaikovsky (which we know as "Trepak"), and deserves its own article.  I've created a new Tropak article and moved the material into there.  I've also renamed this article "Trepak (Tchaikovsky)" because it's not the only trepak ever written by composers.  It still needs some sources and categorisation.
