Bebop Jazz and its Influence

Bebop was a revolutionary sound that captivated the audience due largely to the new found creative freedom of musical expression allowed by extensive improvisation. According to John Andrews (1998), Bop marked the point at which both the musicians and their audience came widely conscious that Jazz was an art form. Andrews also goes on to mention that bebops mall focus was for people to seriously listen, instead of dancing. After bebop other styles of Jazz developed, such as progressive Jazz, cool jazz, and hard bop. These three styles of Jazz, In the pollen of many people, imparted a substantial influence on current jazz, and will likely impact future generations as well. Bebop is a style of Jazz developed in the early sass as a means to revolt against big band music. Big band music required large groups of players. As a consequence, the musicians were required to follow simpler, highly structured, written arrangements. At the time, many musicians resented the lack of freedom to improvise and the reliance upon written arrangements, so they created bebop, a new style of Jazz. Bebop was vastly deferent than swing band music. It had faster tempos, complex harmonies, elaborate melodies and a rhythm section. According to _Americas Musical Landscape-? a typical bebop combo consisted of a trumpet, saxophone, double bass, piano, and percussion. Due in part to the smaller number of performing Caucasians, bebop music allowed for more freedom of expression and imagination than in big band music.Improvisation was a key feature. While much of big band music was designed to indulge the audiences desire to dance, bebop Jazz is for people who want to sit down and listen to the music. At first, many people enjoyed listening to bebop simply because it was something new and exciting. However, many people, particularly musicians, prefer bebop because of its sophistication and complexity. Some Jazz musicians felt they needed something different and preferred to play bebop Instead of swing Jazz to demonstrate their improvisational skills.Musicians such as saxophonist, Dizzy Gillespie; trumpeter, Charlie Parker; and plants, Theologies Monk; stand out as examples of creative giants who through their virtuosity, were able to achieve an innovative sound that wound into their musical presentations, more important than dancing or chatting ove r simple background music. In a way, bebop was a new genre unto itself, more akin to Jazz than big band music. Because it is essentially the basis for most contemporary Jazz styles, listeners will hear the enduring influence of bebop in most Jazz forms that have followed it.Progressive Jazz, cool Jazz, and hard bop are three styles to have evolved from bebop jazz. It is likely that these three Jazz styles, as well as others, embedded with the underlying roots of bebop will have an ongoing influence on future Jazz musicians. No one can speak for all musicians, many may prefer to play older well-established, classic Jazz, but certainly there are a substantial number of musicians that prefer playing the avian-garden styles, who will carry the flag of bebop for future generations.Bebop was a revolutionary and exciting sound that changed the world of Jazz in the asss and continues to influence Jazz styles today. At its advent, bebop was a way for jazz musicians to break away from the confines of big band music, wh ich did not allow for much improvisation or freedom of musical expression. Bebop pioneers such as Charlie Parker, Dizzy Gillespie, and Theologies Monk helped pave the way for other jazz musicians, allowing them to shed their restrictive chains of structured big band music and to elevate the level of improvisational genius that bebop allows.

Properties of Materials - Essay Example There are two rules of thumb that have been given in comparing the density of materials i.e. titanium is nearly half the density of steel and that of aluminum is about one third the density of steel. Any heavy and weak material is considered bad but for a strong and light material is considered good. Stress and strain Stress has been described as the amount of force applied to a certain material divided by the cross sectional area of the material to the direction of the force. Strain properties, on the other hand, indicate how much a material lengthens under stress. Tensile and comprehensive strength The strength of a material can be measured by putting a material sample in a powerful materials testing machine, which pulls the materials apart and then records the force required to do so, plus the deformation to the material. Compression strength is determined by subjecting the material under pressure until it breaks i.e. heat, impact, et cetera. Tensile and compressive indicators are then recorded. These are good measure of how much impact the building materials can withstand without breaking if subjected to certain pressures (James, 2011, 35). Elastic and plastic deformation As explained in the stress strain diagrams above, elasticity and plastic deformation occurs prior and after application of a certain amount of stress on a certain material. In figure 2 above, below point A, we find that steel goes back to its original state hence it is elastic. Beyond point B, the steel cannot go back to its original length hence it is deformed or inelastic. Permanent elongation of a material is called plastic deformation. The same case applies to other building materials under different stress conditions. Below is the load deformation curve: Modulus of elasticity This is a coefficient which denotes the ratio of stress per unit area acting on, to cause deformation on a material to the resulting deformation therefrom. The elastic modulus, E, is usually determined after the compression tests are done on buildings. It differs in various types of materials for building. Elasticity modulus for steel is determined during manufacture while that of a concrete wall is calcula ted depending on the building dimensions. Task II Figure three: Graph of load against extension See the excel attachment Modulus of elasticity, E E = 2G(r+1) where G is the modulus of rigidity and r is the Poisson’s ratio. E= (F) (L1)/ (A) (L2) where F is the force or load, L1 is the original length of material (in this case mild steel), L2 is the amount the length changes on application of the load, A is the cross section area that the force is applied on the material. Area of the rod steel is given by the formula:, then A= 22/7* 12.52 = 491.07 mm2 E = {[50*195] / [491.07*0.09] + [100*195] / [491.07*0.19] + [150*195] / [491.07*0.29] + [160*195] / [491.07*0.34] + [165*195] / [491.07*0.46] + [170*195] / [491.07*0.78] + [180*195] / [491.07*0.84] + [190*195] / [491.07*0.91] + [200*195] / [491.07*0.98] + [210*195] / [491.07*1.07] + [220*195] / [491.07*1.24]

Review of a presentation - Essay Example The progress in the identification and discovery of the lupus disease has paved the way for immunology application in its study thus making the foundation for its current treatment. The disease has shown uneven prevalence interns of race and gender. It is more prevalent in black American women their white counterparts. Lupus is classified in to five types where each type presents different signs and symptoms and causes. This type includes Discoid lupus erythematosus, subacute cutaneous lupus erythematosus, drug-induced lupus, neonatal lupus and SLE (systemic lupus erythematosus. The real cause of lupus has not been established yet. This is so due to the many factors that are contributed with the real development of and diagnosis of the disease. Currently, there is no single specific test for the disease and it can last some time before it is established. These calls for several tests to establish the disease like Medical history, Blood tests, ANA test, Skin Biopsy and Kidney biopsy. The disease manifest itself in different symptoms like pain or swelling in joints, muscle pain, fever with no known cause, red rashes, most often on the face, chest pain when taking a deep breath among others. The disease is believed to be caused by epigenetic factors, which are demonstrated by a study of a set of chemical reactions that switch part of the genome on and off at a strategic location and time. Lastly, the re is no cure for the disease but the most applicable treatments aims at treating the symptoms. Evaluation History of lupus The history of lupus disease can be split in three broad periods: Classical era- this period is dated back in the 13th century where the name of the disease was coined. Several physicians gave the disease different names depending on their own thoughts and presentation of the disease. Example of these physicians was Rogerius in 13th century who coined the name lupus describing the facial lesions caused by the disease. Neoclassical Era- this perio d began back in 1872, and it was marked by description of the disease’s dissemination manifestations by Osler. Modern era- this was marked by the discovery of LE cells in1948 in the bone marrow of patients with acute disseminated lupus erythematosus by Hargraves and his colleagues. This was followed by the discovery of immunology of the disease by Moore in 1950’s and systematic occurrence of the disease in patients by Arnett and Shulman in 1954. Epidemiology The disease has shown prevalence of 20 to 150 cases per 1000,000 people. Its prevalence is more in African American Women compared to their white counter part at 164 and 406 respectively situation which has tripled for the last forty years. The prevalence of the disease is highly exhibited in women due to their estrogen hormones aged 20-45 years of age. Lupus disease is highly prevalence in Asians, Afro- Americans, Afro-Caribbean and Hispanic Americans. Classification Lupus disease is classified in to five types wh ere each type has its own specific cause. 1. Discoid lupus erythematosus which result in scar causing skin lesion and can lead to the development of SLE. 2. Subacute cutaneous lupus erythematosus. Mostly commonly in women aged 15-40 years of age manifested inform of skin lesions. 3. Drug-induced lupus which is cause by continuous use of specific drugs like procainamide and guanidine. 4. Neonatal lupus. It is passed from the mothers and appears as skin rashes
