Heighten Your Appreciation of Music Music is such a fundamental part of human culture that it likely pre-dates literacy，the invention of the wheel，and even the musical note itself.While people generally know what kind of music they like - and what they don't - it's possible to expand your appreciation by learning new ways to listen.Here are some tips for cultivating sensitive awareness of musical elements.
   You might feel frightened picking up a guitar or sitting down at a piano but learning an instrument can help you better understand how a song comes together and what role a specific type of sound plays in the composition.Moreover，the movement and effort of a live performance can often focus your attention on parts of a song you may have otherwise missed.So，the next time you hear a song一 particularly a classical arrangement-try to imagine it being performed.Or，try to picture a scene（a thunderstorm，a race） that best fits the mood and tempo（節(jié)奏） of the piece.
   It's certainly not necessary to grab your favorite musician's biography in order to appreciate a good simple song.but it may help you better understand the context in which he or she wrote the lyrics or recorded a track.Researching backgrounds can also lead you to discover social and political influences at the time the music was created.
   It could be hard to appreciate a warm day unless you've spent a winter freezing.Likewise，listening to music requires a contrast that helps you better understand how organized and harmonious it can be.Listen to--don't just hear-common，everyday noises.While some may be irritating，others may have a melody all their own.Either way，you'll return to a piece of music with a new respect for a focused，deliberate bit of sound.
