Music is defined as vocal or instrumental sounds combined in such a way as to produce beauty of form, harmony, and expression of emotion, but music is not bound from its meaning. Music can be almost anything a person wants it to be. No one can put a date on when music will begin. Some say it began before humans spread across the world or perhaps originated in Africa. One conclusion that most people would agree with is that music has been around forever. Whether people know it or not, music is a key aspect of their lives and influences them in many ways. One might begin to wonder why humans participate in and enjoy music so much? This question may never have a concrete answer, but many have an idea of ​​what the reason might be. The first is the question: why is music so important to us? Music has always been present and has always been known and appreciated by human beings. The beginning of music is not known, but "[some] suggest that the origin of music probably derives from natural sounds and rhythms" (Wikipedia). Music always seems to be a natural feeling and many people pour their feelings into their music. These emotions create the continuous development of the music. Music is created every day and different forms appeal to different people. Although many different musical genres exist today, they all have the same roots. Music can be defined as noises put in order. Noise is everywhere, in some places more than in others. Noises are not noises unless there is something that hears them. This confusing statement is often questioned, as when someone asks, “Does it make a noise if a tree falls?” According to Daniel Levitin and physics, the answer is no. “…vibrating air molecules are what reach our eardrum, and…the center of the paper…and Songs from Your Past evoke such vivid memories?”.
