Elite Syncopations is one of several popular piano rags by composer Scott Joplin and it was first published in 1902. The "Syncopations" in the title is a direct reference to the bouncing off-beat rhythm which characterises Ragtime Music. In the 1970s the choreographer Kenneth MacMillan launched a ballet called "Elite Syncopations" based on a range of ragtime pieces by Scott Joplin and other composers. The ballet was well received in London and went on to be staged in the US and Canada. The ballet is discussed at the beginning of this youtube video which includes some short excerpts from the ballet.
