Jazz in America essays

Jazz in America essays Jazz is a mixture of culture, rhythm, and blues. It is a melting of many different people and there heritage. This American musical form often-improvisational development by African Americans, and influence by both European harmonic structure and African rhythms. During the 1800 in Americas south, music was an integral part of the life of the plantation slaves of African decent. Plantation songs, spirituals, and field were a part of everyday life-to celebrate, to morn, to entertain, to commemorate, to worship, and to accompany the drudgery of the work. The music of the plantation blended with European-American music tradition to create the basis of blues, ragtime, and other musical forms from which Jazz evolved. Ragtime from 1880-1900 was one of the early musical styles that contributed to the development of jazz. This music was developed in New Orleans during the late 1800, it was composed primarily for the piano. It combined a 16 note based syncopated melody with the form and feel of a march. On the piano this was achieved by pianoist left hand playing a steady boom-chic bass and cord pattern, and the right hand playing the tune. Playing in this style was called ragging. Noted piano players of this style were Scott Joplin, Artie Matthew, James Scott, and Tom Turpin. The Blues from 1900-1920 was an important influence on the development of Jazz. A highly expressive vocal tradition, blue songs express story and emotions. The blues were not only a type of music, but a state of mind and the way of life for many Blacks during this time. This music was seen by Northern American and became very popular. This was the beginning of the jazz age with Louis Armstrong, the Charleston, and flowering dresses with no waistline. Louis Armstrong was the first important soloist to emerge in Jazz. In the 1920 in a studio recording he made his hot five and hot seven ensemble. He ...

An Overview of Biomes and Climate

An Overview of Biomes and Climate Geography is interested in how people and cultures relate to the physical environment. The largest environment of which we are part is the biosphere. The biosphere is the part of the earths surface and its atmosphere where organisms exist. It has also been described as the life-supporting layer that surrounds the Earth. The biosphere we live in is made up of biomes. A biome is a large geographical region where certain types of plants and animals thrive. Each biome has a unique set of environmental conditions and plants and animals that have adapted to those conditions. The major land biomes have names like tropical rainforest, grasslands, desert, temperate deciduous forest, taiga (also called coniferous or boreal forest), and tundra. Climate and Biomes The differences in these biomes can be traced to differences in climate and where they are located in relation to the Equator. Global temperatures vary with the angle at which the suns rays strike the different parts of the Earths curved surface. Because the suns rays hit the Earth at different angles at different latitudes, not all places on Earth receive the same amount of sunlight. These differences in the amount of sunlight cause differences in temperature. Biomes located in the high latitudes (60Â ° to 90Â °) farthest from the Equator (taiga and tundra) receive the least amount of sunlight and have lower temperatures. Biomes located at middle latitudes (30Â ° to 60Â °) between the poles and the Equator (temperate deciduous forest, temperate grasslands, and cold deserts) receive more sunlight and have moderate temperatures. At the low latitudes (0Â ° to 23Â °) of the Tropics, the suns rays strike the Earth most directly. As a result, the biomes located there (tropical rainforest, tropical grassland, and the warm desert) receive the most sunlight and have the highest temperatures. Another notable difference between biomes is the amount of precipitation. In the low latitudes, the air is warm, due to the amount of direct sunlight, and moist, due to evaporation from warm sea waters and ocean currents. Storms produce so much rain that the tropical rain forest receives 200 inches per year, while the tundra, located at a much higher latitude, is much colder and dryer, and receives just ten inches. Soil moisture, soil nutrients, and length of growing season also affect what kinds of plants can grow in a place and what kinds of organisms the biome can sustain. Along with temperature and precipitation, these are factors that distinguish one biome from another and influence the dominant types of vegetation and animals that have adapted to a biomes unique characteristics. As a result, different biomes have different kinds and quantities of plants and animals, which scientists refer to as biodiversity. Biomes with greater kinds or quantities of plants and animals are said to have high biodiversity. Biomes like the temperate deciduous forest and grasslands have better conditions for plant growth. Ideal conditions for biodiversity include moderate to abundant precipitation, sunlight, warmth, nutrient-rich soil, and a long growing season. Because of the greater warmth, sunlight, and precipitation in the low latitudes, the tropical rainforest has greater numbers and kinds of plants and animals than any other biome. Low Biodiversity Biomes Biomes with low precipitation, extreme temperatures, short growing seasons, and poor soil have low biodiversity fewer kinds or amounts of plants and animals due to less than ideal growing conditions and harsh, extreme environments. Because desert biomes are inhospitable to most life, plant growth is slow and animal life is limited. Plants there are short and the burrowing, nocturnal animals are small in size. Of the three forest biomes, the taiga has the lowest biodiversity. Cold year-round with harsh winters, the taiga has low animal diversity. In the tundra, the growing season lasts a mere six to eight weeks, and plants there are few and small. Trees cant grow due to permafrost, where only the top few inches of the ground thaw during the short summer. The grasslands biomes are considered to have more biodiversity, but only grasses, wildflowers, and a few trees have adapted to its strong winds, seasonal droughts, and annual fires. While biomes with low biodiversity tend to be inhospitable to most life, the biome with the highest biodiversity is inhospitable to most human settlement. A particular biome and its biodiversity have both potential and limitations for human settlement and meeting human needs. Many of the important issues facing modern society are the consequences of the way humans, past and present, use and change biomes and how that has affected the biodiversity in them.
