Improvisation stands at the centre of Chopin's creative processes. However, this does not imply impulsive rambling: Nicholas Temperley writes that "improvisation is designed for an audience, and its starting-point is that audience's expectations, which include the current conventions of musical form." The works for piano and orchestra, including the two concertos, are held by Temperley to be "merely vehicles for brilliant piano playing ... formally longwinded and extremely conservative". After the piano concertos (which are both early, dating from 1830), Chopin made no attempts at large-scale multi-movement forms, save for his late sonatas for piano and for cello; "instead he achieved near-perfection in pieces of simple general design but subtle and complex cell-structure." Rosen suggests that an important aspect of Chopin's individuality is his flexible handling of the four-bar phrase as a structural unit.

Rosen suggests that a central part of Chopin's uniqueness is how he handles what?

Structural material that resembles ordinary, "dicot" or conifer wood in its gross handling characteristics is produced by a number of monocot plants, and these also are colloquially called wood. Of these, bamboo, botanically a member of the grass family, has considerable economic importance, larger culms being widely used as a building and construction material in their own right and, these days, in the manufacture of engineered flooring, panels and veneer. Another major plant group that produce material that often is called wood are the palms. Of much less importance are plants such as Pandanus, Dracaena and Cordyline. With all this material, the structure and composition of the structural material is quite different from ordinary wood.

What type of plants produce material that is referred to as "wood" even though it is technically not?
Answer: monocot

New Haven is the birthplace of former president George W. Bush, who was born when his father, former president George H. W. Bush, was living in New Haven while a student at Yale. In addition to being the site of the college educations of both Presidents Bush, as Yale students, New Haven was also the temporary home of former presidents William Howard Taft, Gerald Ford, and Bill Clinton, as well as Secretary of State John Kerry. President Clinton met his wife, former U.S. Secretary of State Hillary Rodham Clinton, while the two were students at Yale Law School. Former vice presidents John C. Calhoun and Dick Cheney also studied in New Haven (although the latter did not graduate from Yale). Before the 2008 election, the last time there was not a person with ties to New Haven and Yale on either major party's ticket was 1968.
