Answer:
World War.
Explanation:
First world war ended in 1918.
I'm assuming you are talking about the American Civil War. There is still a certain level of racism in the South that was heightened by the Civil War and the Southern economy is not as good because they are still behind industrially because they relied so heavily on cotton around the time of the war. Also punishments from Reconstruction and the increased industrialization in the North that occurred as a result of the war has and will continue to hurt the South.
The final solution during World War Two was hitlers plan for mass extermination of the Jewish people by using the gas chambers where he could kill ultimately millions of Jews and other minorities.
1.melody short phrases, large leaps
Towards the end of the past century composers as Steve Reich La Monte Young, Philip Glass, they began to explore what is now called minimalism, in which the music is stripped down to its most fundamental features; the music often features repetition and iteration. An early example is Terry Riley's In C from 1964, perhaps a random work in which short phrases are chosen by the musicians from a set list and played an arbitrary number of times, while the note C is repeated in quavers behind them. Philip Glass works are on the most representative perhaps also featuring as soundtracks of movies.
2, harmony mixed meter
This caused a very new sensation with an extreme irregular rhytm. While time signatures usually express a regular pattern of beat stresses continuing through a piece (sometimes a section), sometimes composers place a different time signature at the beginning of each bar, resulting in music with an extremely irregular rhythmic feel.
Examples;Promenade -- Modest Mussorgsky's Pictures at an Exhibition (1874) The opening already shows signs of this implement
3· rhythm atonality
Atonality first began as a pejorative term to condemn music in which chords were organized seemingly with no apparent coherence. the term describes music that does not conform to the system of tonal hierarchies that were traditionally seen in classical European music between the 1700's and 1900'a centuries Example; ending Schoenberg's "George Lieder" Op. 15/1
4.dynamics extremes
some pieces started to use additional markings of further emphasis. Extreme dynamic markings introduced an extreme range of loudness, or, and sometimes accompanied with very small differences of loudness within a normal range, this huge change was made possible with the orchestration of the work, usually using many loud instruments like brass and percussion playing at once. It became more widespread in late 1900s.
