Recordings and how it effects us

Lately in class we have been talking about recordings in class. This topic has honestly shaped our society today into what it is. Without recordings many would be lost. Mainly recordings involve music but it also can involve radio and movies. Without recordings many privileges we have today would not be here. Thomas Edison created the idea of recording stuff in 1877 , but the first known music to be recorded was in 1888. Other then audio recording it the only other way to record it is to write it down. But the difference between audio recordings and written recordings is audio you can get the feel for the music better then if it was just on paper.
The first thing to record music was called a phonograph. The phonograph was basically a foil cylinder. Right before the first known price of music was recorded Berliner came out with a gramophone that could allow you to listen back to the recording as much as you want. This is a huge difference from the phonograph where it could break easily so you could only play it back so many times.
Between music radios and movies recordings keep us pretty occupied. But truely why have recordings been around for so long? Well we use them for many different reasons. Each recording has it's own purpose and own message. We can use recordings for many things such as entertainment, religion, propaganda and education.
In my opinion this lesson was very informative. But I still do not understand why we keep bringing up the timelines. If they are not important then why give us fluff information. Other then that I feel everything said in this lecture was very informational and important. I feel that as we do more lectures I am retaining more and more information. This style of learning is starting to help me more and more as we do it.
