What are the details about the transition from the Classical Era to the Romantic Era in the arts.

Although the terms "Classical" and "Romantic" are often
used to describe periods in artistic history, they are also approaches to art.  Art of
the classical approach will emphasize orderly, balanced forms depicted in an objective,
rational way.  Classical art is often associated with the Age of Reason, also known as
the Enlightenment, when thinkers and philosophers such as John Locke, Jean Jacques
Rousseau and even Ben Franklin were ruminating in writing on the possibilities of the
human mind and questioning traditional religious beliefs in light of new scientific
knowledge and understanding. The classical art forms often recall the work of the
Greeks, with an emphasis on the beauty and harmony of the human form and the symmetry of
classic architecture.  Classical music is characterized by brief, uncomplicated melodies
and repetition of such, while classical paintings tend to be constructed with symmetry
and balance, realistic forms and classic architectural features such as columns and
arches. 

Romantic artistic approaches tend to reject the
realism of classicism, focusing instead on feelings, emotions, images that appeal to the
senses, a subjective point of view in contrast to the objective point of view of the
classicists.  A romantic painting will have less defined forms, and often depicts
feelings that are often gloomy, dark, pessimistic.  Romantic music, similarly, will be
characterized by long, often brooding, melancholy melodies and changing tempos and
volumes. In contrast to Classicism, the emphasis is on feeling over
form.
