Bluegrass performance - Essay Example The music has long been influenced through jazz by the African-Americans and other migrants (Nemerov, 2009). Traditional acoustic stringed instruments are used to play bluegrass music. Instrumentations such as mandolin and five-string banjo accompanied by harmonica and Dobro (resonator) were used in the ancient traditional dance bands and influenced the current bluegrass bands. The currently flat picking style of playing the guitar evolved from the ancient thumb and finger picking (Cantwell, 2002). This was introduced by Earl Scruggs who influenced the three-finger pick. Despite the recent introduction of new grass due to electronic versions and new instruments such as harmonica, traditional instruments are still used and culture maintained. The theme of bluegrass music revolves around narratives about the people who first developed the music. The vocals in the music are a representative of the hardships that people of Appalachia in the ancient days and other rural areas went through living with limited financial resources. However, the currently evolving music includes interpersonal tensions, resistance to changes like the mountaintop coal mining and laments on love that was lost are part of the theme. The Appalachia railing of roads is also an integrated theme as performed by ballads like Nine pound hammer, form John Henry legend and Wreck of the Old 97. The vocal harmony, apart from instrumentation displays Bluegrass music as a cultural product. The high lonesome sound style represents the hardships that the ancient Appalachia people used to go through living with less financial resources. The style includes dissonant sound on the highest produced by two to four parts (Olson, 2006) . The baritone voice in the stack played in the 1950s by the Stanley brothers is still played and some parts added to the traditional parts. Currently, museums are

Cause and Effect and Correlation Essay Example | Topics and Well Written Essays - 250 words

Cause and Effect and Correlation - Essay Example An article published by the John Hopkins University (2000) indicated that â€Å"predominantly black, low-income neighborhoods in Baltimore were eight times more likely to have carry-out liquor stores than white or racially integrated neighborhoods† (John Hopkins University, 2000, p. 1). Bradtmiller cited Interim Chief of the IU Police Department Jerry Minger as stating that â€Å"There are so many factors that are involved in violence,† Minger said. â€Å"It could be something like a domestic problem or a hate crime and have not anything to do with alcohol† (Bradtmiller, 2010, p. 1). Again, one agrees that the abundance of liquor stores is a contributory factor to criminal activities. In higher crime areas, there are usually more police; does that mean that police cause crime? This statement is totally unfounded, unsubstantiated and does not indicate any correlation to criminal activities. The reason why police presence is needed is to specifically address the crimes committed in high crime areas. There could be a correlation that when there are high incidents of crime, there would necessarily be greater number of police to address the criminal activities in the area. To determine a reliable correlation between the number of liquor stores and the number of crimes in low income neighborhoods, what kind of experiment might you design? A correlation analysis between two variables (number of liquor stores and number of crimes) would determine a reliable correlation between the two. What kind of correlation number would make you feel fairly certain that there is a solid connection between larger numbers of liquor stores in low income neighborhoods and resulting crime? The correlation number ‘r’ (Pearson r) would establish whether there is a solid connection between the two variables. As revealed in Knowledge Base (2006), â€Å"r will always be between -1.0 and +1.0. if the correlation is negative, we have a negative relationship; if its positive,
