Math and Music Essay - 447 Words

Math and Music When you listen to a piece of music you usually don’t think of math, but the two are interlinked and music always involves math even though we don’t always realize it. When musicians play music they are using mathematical formulas to play. There are formulas for making cords, scales and a formula for the what notes they play. Musical notation also involves math, you use time signatures while playing along to a piece of music which are basically just fractions, 3/4,7/4, and 4/4 are all time signatures. the bottom number in the fraction gives you the type of note to be played and the top gives you the amount of times it is played. There are five basic types of notes to be played in music, the sixteenth note, the eighth†¦show more content†¦This is how most musicians make a cord. The first note in the scale is always a full tone as is the last this is because this is two octaves apart and they are the root notes. (guitar player, June 1996) There are twelve tones in an octave ex. C, C#, D, D#, E, F, F#, G, G#, A, A#, B. A full octave would have another C at the end but it is the same pitch as the first C except an octave higher so it is usually left out. Ancient Greeks came up with this method, they said in an octave each note was an integer multiple of the first. There is not a perfect octave however it is always a couple of numbers off the original frequency. log3/log2= continued fraction[1,1,1,2,2,3,1,5,2,23,...], is the best fraction to get closest to the perfect octave. if we take the notes frequencies, and build fifths we get pretty accurate to a perfect octave. Twelve is by far the easiest number to get closest to a perfect octave which is why there are twelve tones in an octave. A whole tone is usually from one whole note to the other or one # note to the other except on tow occasions: b-c and e-f there is no # note in between those notes so from b-c and e-f is a whole tone but anywhere else it is three notes ex. a-a#-bShow MoreRelatedThe Math in Music584 Words   |  2 PagesMusic with Math Few people understand that music is actually connected to math. Most people i believe have more of an idea of what music is than what they know what math is. Music is scales and notes. Math is numbers and symbols. Deep in the core of music, music is really math. They also have a strange connection: Music is the only art form where the form and the medium are the same. Math is the only science where the methods and the subject are the same.

Personal Account of a Woman in the American Revolution Free Essays

I was a woman who had lived during the boisterous era of the American Revolution. It was a time when not only men were needed to gain the most coveted American independence from Britain. We will write a custom essay sample on Personal Account of a Woman in the American Revolution or any similar topic only for you Order Now One might wonder how a woman with no weapons or battle skills could contribute in the realization of American independence. As a woman of the 18th century, I was an ordinary housewife tending to my husband who was continuously fighting in battle against the British. I was always following him just as any woman and wife did for their men in battle. My husband’s task was to load the cannon so the gunner could fire a shot towards the British army. One fateful day, I saw how my husband was killed by a gunshot which ultimately ended his life. I was there trying to mend his wounds despite the fact that he was already dead. While I was in the middle of finding a place where I could place my husband safely in the barracks, the gunner summoned me to load the cannons. Everything was happening so fast that I had no time to think about my dead husband’s body. All I wanted to do was to fight for what he died for. I hurried to the cannon as fast as I could and loaded the cannon. It was not an easy job to lift cannon balls, but the raging adrenalin in my system helped me throughout. The cannon loading went on for a week until they finally found a more capable man to replace me. Afterwards, I was given the task to tend to the American soldiers. I cooked for them, washed their clothes, attended to their medical needs, and cleaned their wounds. We were like nurses and housewives in one who provided all the basic needs that our soldiers called for. It might have seemed like a simple job to take care of these wounded men as they have fought and died for the country’s liberty. However, one thing is for certain. The Declaration of Independence would not have existed without the full support and love of women in the American Revolution.

Now that Im a High School Senior Essay Example For Students

Now that Im a High School Senior Essay After about 12 years of hard work and education, I am finally a senior. I am at the top of the high school hierarchy. I remember watching my siblings graduate and thinking, †When will it be my time? Now, all of a sudden, it is! This year is a year of lasts; last first day of high school, last exam, last prom, last paper. It is a scary thought, but also exciting. This year is going to be one of the most emotional and crazy years of one’s life. It is a year of reflection on what goals, fears and plans are for the future. My senior year, compared to others, is a little bit different. I can say it has been a big adjustment. I just recently moved from Cary, North Carolina to Parkersburg, West Virginia. So, although it is a year of â€Å"lasts†, it is also a year of â€Å"firsts†. I already miss things from where I lived before. I constantly think about my friends back home and remember all the great times we had. Also, I miss my family that has been there for me through thick and thin. It really isn’t that easy to stop those nostalgic feelings from forming. I don’t know if one calls that easier or harder to leave for college because I somewhat know what it feels like. I don’t have those established relationships and connections here. Is this going to be another hit to the heart because I will eventually grow to love them too? Those thoughts are constantly in my head, like a broken record player. One of my fears of being a senior is Senioritis. I am afraid that once I get accepted into a college I will suddenly get the feeling that I have done it all and its time to coast and enjoy myself. I can’t afford to that. With two advance placement classes, two college courses, and a significant number of electives, I have to constantly be on my toes. From here on out, it seems like it will become a sprint. I will have to get the grades I need, get all of my applications filled out and be sure to keep getting enough sleep throughout the process. I am doing my best to stay ahead of the game. I tend to be a bit of a procrastinator, so the more I can stay ahead, the more prepared I will be for whatever else comes at me. Another fear that comes to mind is how much I am going to miss my mom. I have always been excited to live in my own place, have a job, and earn my own money. But it makes me sad to think that this is the last chance I have to spend a lot of time with her. Have I taken full advantage of the time I’ve had? Of course it’s fun to think about being independent and responsible, but it’s not fun thinking I can never go back. I will no longer be a child she can rescue. I will be an adult, and will be on my own The most frequent question a senior asks his or herself is â€Å"what am I going to do after high school? † My dream is to help people. My goal is to become an orthopedic surgeon. Once I attain this, I want to go into the military and use my skills as a surgeon. It would not matter where I was living as long as I am making a difference in the world. This dream partially came from my mom because she helps and makes a difference everyday as nurse. I have so much respect toward her. She inspired me to help those who cannot. I have always wanted to go into the military. It was a calling. Something deep inside said this is that path I need to take. Throughout the years my determination for this dream to come true only gets stronger and stronger. I would like to go to college at NC State, UNC, or Wilmington. From there I would study pre-med and a military science program. After that, medical school and enlist in the navy. .u291215c9757cf517c6f2062d50e48835 , .u291215c9757cf517c6f2062d50e48835 .postImageUrl , .u291215c9757cf517c6f2062d50e48835 .centered-text-area { min-height: 80px; position: relative; } .u291215c9757cf517c6f2062d50e48835 , .u291215c9757cf517c6f2062d50e48835:hover , .u291215c9757cf517c6f2062d50e48835:visited , .u291215c9757cf517c6f2062d50e48835:active { border:0!important; } .u291215c9757cf517c6f2062d50e48835 .clearfix:after { content: ""; display: table; clear: both; } .u291215c9757cf517c6f2062d50e48835 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u291215c9757cf517c6f2062d50e48835:active , .u291215c9757cf517c6f2062d50e48835:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u291215c9757cf517c6f2062d50e48835 .centered-text-area { width: 100%; position: relative ; } .u291215c9757cf517c6f2062d50e48835 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u291215c9757cf517c6f2062d50e48835 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u291215c9757cf517c6f2062d50e48835 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u291215c9757cf517c6f2062d50e48835:hover .ctaButton { background-color: #34495E!important; } .u291215c9757cf517c6f2062d50e48835 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u291215c9757cf517c6f2062d50e48835 .u291215c9757cf517c6f2062d50e48835-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u291215c9757cf517c6f2062d50e48835:after { content: ""; display: block; clear: both; } READ: Minimum Wage EssayFrom there live out my dream and make a difference in the world. Hopefully, I can keep things together in my final year in high school. This is the last time to get it right. I have big dreams that I am eager to fulfill. Even though I am new, I look around the high school sometimes and realize that next year I won’t be here. A year ago I could not even wrap my head around that concept. Now I am a senior, like it or not every day the future becomes more real. The idea of college and life after college becomes less of an intangible fantasy and more of a hard reality.
