C. Music's influence

When we listen to music, we can internalize, so that the emotions of the composer, the band or singer, become a part of us. For the time we listen to and identify with the music, we have a spiritual connection, a bonding, with the one or ones who are singing, playing, and/or who composed the music.

Music can be interpreted in different ways. Even the same music performed by the same composer, can convey a message of sadness and loyalty, or anger and betrayal, depending on the manner in which he chooses to convey the message.

Music can be used in a positive way to bridge gaps, to create a bond between people who might otherwise have little in common. It can convey a message of peace and brotherhood, relax, soothe.

At the same time, music has been used historically to glorify war, such as in the Star Spangled Banner which recalled the victory of the Americans over the British in the War of 1812, or when classical pieces by German composer and theatre director Richard Wagner (pronounced Vagner), were used by Hitler to stir patriotic fever in the masses.

Children, teens, and even babies potentially benefit from listenening to music, as music can be a stimulant to intellectual and cognitive development. 

At this point we most say that music has a great influence on teenagers behavior. from how they dressed up to what they say, it all goes around music. so that it can be positive or negative, as we said before. 

It is positive when makes them be gentle and obedient. And it can be negative when they tend to be agressive,   possesive, and rude.
