Its influences are closely related to each other. Rap music has derived from various types of music. In a world in which people are constantly confronted with violent acts such as rape, assault, murder, school shootings, and other violence.

Rap paints a picture to a child of what is going on in the streets. It has a much bigger influence on teens because children who live in poverty strictened areas already have an idea of what that life is really like.

Hamlet

...Annotated Bibliography for Hamlet Thesis: In Hamlet, Ophelia faces the constant struggle to find her identity, due to male superiority and lack of mother. If Ophelia were to live in today’s world, she would most likely suffer from depression, abuse, and eating disorders due to her lack of personal identity. Shakespeare, William. Hamlet. New York: Dover Publications, 1992. Print. Hamlet, by William Shakespeare is the main text used for relations to Ophelia and her lack of personal identity. This play provides us with first-hand information on Ophelia’s downward spiral into insanity, which results in her own personal demise. This source is very appropriate, due to the fact that it is the first-hand insight into what Shakespeare portrayed Ophelia as, in her role in Hamlet. Therefore, it is believed that all information found in it, can be trusted and used accordingly, to relate Ophelia and her insanity due to contributing factors in her social environment. I found this source, in class, as it was our primary learning source in the discussions we had about Hamlet. This source is unlike my other sources, due to the fact that it is the base text for my work. From this source, I can learn how Ophelia slowly fell into madness, and what events helped lead up to her peak of insanity in the play. This helps develop my essay, because it is the main source that I will be using in relation to my other research sources. Considering that this is my base text, it is relatable to both......

Explicit Lyrics

...Explicit Lyrics With a Meaning Censoring explicit lyrics from young people is a debatable decision. In some ways, it can be beneficial due to the harsh and inappropriate content, and in other ways, it could be bad to censor explicit lyrics because they could send out a powerful and meaningful message. Explicit lyrics should not be banned or censored from young people because they could send out content that means something to that person and/or to their history, or that it could mean something for an entire community or culture. Lyrics found in rap music can help someone understand and sympathize with what the rapper is feeling. If people were to stop focusing on the negatives of rap music and start looking at the positives, they would have better respect towards rap music all in all. Some songs give out so much meaning that could influence a child to feel something towards that song and relate it to their own life and act upon their life as if it is being described in the song they listen to. Explicit lyrics have been around for many years and have given out a message to those who can feel exactly what the rapper is feeling. Even though rap music with explicit lyrics have had been given a bad reputation in society, “raps popularity can be useful in opening adolescents up to being more expressive” (Wiley 1). Parents are trying to understand the concept of explicit lyrics and how they can be beneficial for their child, but in reality, they’re only paying attention to the...

Religion, Diversity, and Hip-Hop

...The impact of religion is sometimes apparent in many different forms of art. One type of artistic expression that religion is sometimes expressed in is music. Whether it is specifically Christian-based music or secular, musicians of all genres may eventually write a song or sing about their religious beliefs at some point. There is a very broad spectrum of diversity in music. People from all around the world with different backgrounds, race, religion, and style can express themselves in this form. Growing up I was exposed to many different genres of music. Hip-hop, which is classified as a subculture that originated from an African American community in the 1970’s, has always been intriguing to me and is a huge part of who I am. There are four elements of Hip-Hop; rapping, DJing, break-dancing, and graffiti. I will be focusing on the music aspect of Hip-Hop and the large impact religion has on some of these artists that perform Hip-Hop music. Over the years, Hip-Hop music has gained a bad reputation. Many people find the lyrics to be offensive, obscene, or even racist. A very small portion of it is, but most of it is the complete opposite. Matthew Paul Miller, better known by his Hebrew stage name Matisyahu, is known for the positive messages he delivers through his reggae-rap style music. Matisyahu says his Jewish spirituality has most, if not everything to do with the way he writes music. In his song “Jerusalem”, he raps about ancient history and religious acts that......

Culture Wars

...Culture Wars Culture wars; there have always been a variety of music to listen to such as Country, Pop, Latin, Hip Hop and Rap. The meaning of culture wars to me is people who dislike a certain genre for instance rap music. Some people are against rap music because of the controversial meaning that songs have. In this paper you will be reading on an interview for Foxx 11 news with O’reily interviewing rap icon Cameron and CEO producer Damon Dash. Principal Salome Thomas-EL asked a couple of questions stating that gangster music is a terrorizing impact on his students, On my opinion you can never tell a rapper they have a negative effect on the youth. It’s their work and their art and what they do as a musician. For example when you hear the stories of kids shooting up a school, was it the rap music they listen to? No, it is the parent’s responsibility to moderate what their kids listen to, it’s wrong for people to blame rappers for the actions that people make. O’reily interviewed rap icon Cameron and CEO producer Damon Dash. During this interview there was also a principal from an elementary school who had questions for the rap stars. The principal complained that the kids at his school look up to the rap star and he thinks Cameron is showing a bad example.

Cameron replied that his music is just what he see’s and what he goes through as a person. ...

Nasty Nas

...Nafees Bost Professor Jordan-smith English 112 15 April 2013 Nasty Nas Quite possibly the only man to indirectly steal my attention with sheer words alone, such a man would have to be non-other than Nas, or Nasir bin Olu Dara Jones. Born the son of jazz musician Olu Dara, Nas dropped out of school in the eighth grade, trading classrooms for the streets of the rough Queensbridge projects, long fabled as the former stomping ground of Marley Marl and his Juice Crew as immortalized in "The Bridge." Despite having dropped out of school in the eighth grade, Nas developed a high degree of literacy that would later characterize his rhymes. At the same time, though, he delved into street culture and flirted with danger, such experiences similarly characterizing his rhymes. His synthesis of well-crafted rhetoric and street-glamorous imagery blossomed in 1991 when he connected with Main Source and laid down a fiery verse on "Live at the Barbeque" in which earned him instant respect among the East Coast rap scene. Not long afterward, MC Serch of 3rd Bass approached Nas about contributing a track to the Zebrahead soundtrack. Serch had been the soundtrack's executive producer and, like much of New York, had been impressed by "Live at the Barbeque." Nas then submitted "Halftime," and the song had impressed Serch enough for him to make it the soundtrack's leadoff track. Columbia Records meanwhile signed Nas to a major-label contract, and many of New York's finest producers......

How Far Do You Agree the Sources Suggest That Attlee Was Not a Very Effective Political Leader?

...How far do you agree the sources suggest that Attlee was not a very effective political leader? To a certain extent Sources 1, 2 and 3 all show evidence that would agree with the statement that Attlee was not a very effective political leader. For example all 3 sources suggest that he lacked authority and power, some of the qualities that would produce a great leader. Both sources 1 and 2 describe Attlee as a ‘small’, ‘shy’ man, giving off the impression that Attlee was a very timid character, not capable of running a country and unable to hold a position of power. Source 1 was written by a supporter of Attlee opponents, so may be untrustworthy, as Kingsley Martin opposed Attlee. Although source 2 was written by a left-of-centre newspaper, adding credibility to the source as the criticisms where from a supporter of Attlee. Meaning that the evidence was not be over exaggerated. However the source was written the day after Attlee resigned meaning that the source could be seen as over-generous, as it is looking back over Attlee’s ruling. Both sources 1 and 3 describe Attlee as a school master who is able to ‘restore order’, but ‘did not teach very much’ this displays that Attlee was unable to change or offer opinion. This reinforces the statement that Attlee was not an effective leader. Source 3 also states that Attlee’s summing-up in meetings was often incomplete and he barely produced constructive ideas. This further suggests that Attlee was there to listen, but not to give......

...men say, especially black rappers on how they feel about their fathers, on them being fathers, on their mothers, and the mothers of their children. The key question the author is addressing happens to be “The Black Family”. Specifically how rappers represent or show through their music how it is. This author breaks it down into smaller parts but throughout all the research this is the common thread. For example he references many artists like Nas, Kanye West, Rick Ross and many more, lyrics they have used in songs. The researcher defined these lyrics and explained what these artists were saying through their music about baby mamas, their fathers, their kids, and so on. The most important information in this article is lyrics that rappers have said in their songs addressing different aspects of the black family. For example when it comes to baby mama’s research shows among majority of rappers a negative connotation on how they feel toward them or disappointment of what they could have been if they weren’t such hard obstacles.

"From Fly-Girls to Bitches and Hos" Critical Analysis

...After reading Joan Morgan’s article “From Fly-Girls to Bitches and Hos” we can evidently say what she was trying to tell us. She certifies that women are not respected in rap music. Joan makes a valid point saying “It’s extremely telling that men who can only see us as ‘bitches’ and ‘hos’ refer to themselves as ‘niggas’” referring to the simple truth that one can not love or respect another if they do not first love and respect themselves. This is not an excuse for rappers to degrade women. It is Morgan’s way of trying to understand where the black rapper is coming from and the reasoning behind the misogyny. She points out that by demeaning black people in rap songs, the vocalists encourage racism and stereotypes. She also claims that if women want to be respected they have to start giving men opportunities to do so. For example, half-naked girls in music videos are not doing a good job in stopping men from calling them b-words. Furthermore, Joan mentions the bad state in which rap music is. The lyrics are focused on self-destructive behavior. As she says, rappers show their inner anger, personal problems and even depression through these shocking lyrics. It is their way of presenting themselves. Morgan introduced these propositions by relying on hip-hop music. She gave a couple examples from songs, their structure and main aspects of lyrics. The article also contains declamations of people not related with rap music which gave the whole work truthfulness. She also point......

Rap Music

...If a person was born anywhere between the 1980's to the 1990's, he or she is considered a part of the "Hip Hop Generation". Music is a gift that has been given to us, but the question is, "where is hip hop music going?" Hip-hop is now one of the biggest and fastest growing businesses in the world. It's creativity in sound, and its lyrics has empowered many of today's youth. Lyrically, some of hip-hop's most popular songs and musicians have negatively influenced violence, drugs, alcohol, sex, disrespect for authority, and disrespect for women. For many young children and teenagers, this type of music can create an environment that can become very interfering to their lives and education. Parents always teach their children to “say no” to drugs but the rappers that children look up to are rapping mostly about using drugs and implying to children that it's okay to use them. Therefore, children will listen to the side that has the most influential power to them. Many children, who constantly rewinds songs and memorize the lyrics, are just as equally influenced just as if they were placed directly in front of the violence and sex and observed them. Statistics has proven that many nightclubs that have had violence occur in them have been playing "violent" hip-hop music. Hip-hop is like a strong tornado that constantly sweeps us up and spits us back out. But whom it's sweeping up are the ones who cannot handle the fall once they are thrown back out.
