Step-by-Step Solution:
Step 1 of 3

The Classical Era (1750-1800)  Age of Enlightenment  Rejection of traditional authority principles for human reason, analysis, and individualism. Human control over a rational universe  Galileo Galilei, Sir Francis Bacon, Sir Isaac Newton, Jean-Jacques Rousseau  Denis Diderot- French philosopher, art critic, and author of the first encyclopedia  Challenged aristocracy’s responsibility to common man  Submitted to detention, house searches, and ostracization for authorship  Sonata Form- the structuring of an entire movement into three ordered sections, each based on how it treats the thematic materials, majority of classical movements in sonata form  1. Exposition- introduction of two contrasting themes, the first generally being more energetic and the second more lyrical  a bridge section occurs between each theme  2. Development – exploration of the themes in various keys, rhythms, dynamics, and timbres  often contains a “strum und drang” (storm and drive) quality  3. Recapitulation- restatement of the exposition in the tonic/ home key  may contain coda- an extended conclusion, at the end of the movement  (rests in music can help distinguish sections)  absolute music vs. program music – (in general the classical era = absolute music) music for its own sake vs. music for physical/ storytelling representations Ludwig Van Beethoven (1770-1827)  recognized as a leader of the Romantic movement in music  career divided into 3 sections  early career as Classicist  mid-years as transitionary  late career as Romantic  eventually went deaf, blaming God and fate for the ultimate irony of a genius composer being denied his hearing  Beethoven’s opera depicting true love, symphonies proclaiming man’s ultimate truth in nature and fraternity, and piano sonatas/late string quartets bearing his isolation and solitude become the fundamental qualities of Romanticism Romanticism (1810-1880)  Romanticism  A cultural movement emphasizing solitary emotions in relation to nature and the exotic/supernatural  Reactionary to the logic and reason behind Enlightenment/ French Revolution  Nationalism as important to style  Characteristic of Romantic Music  Melodies are expressive, lyrical, emotional  Rhythm uses more rubato for ambiguity, dance rhythms indicating nationalistic styles  Exploration of instrumental colors  Wide range of dynamics, frequent fluctuations in levels  Art song- musical setting of poem for solo voice and piano  Lied- a German art song  Song cycle- a series of art songs that relate or tell a story  Art songs often performed in Salon setting- gathering in an upper- class home for informal literary/ musical performance by those in attendance  Art Song Form  Strophic- each verse of a poem is set to exactly the same music  Modified strophic- some verses of the poem are set to the same music, while others are set to different music  Through composed- each verse of a poem set to different music, contains sections of narration and dialog  Also the form of Ballard  Franz Schubert
