Sounds are defined by the silence that surrounds them. And in this way silence itself becomes a key element in composition.
The Power of Silence
Imagine an orchestra in a packed concert hall. Think of the pause where the conductor holds his baton raised and the timpanist in the percussion section holds his mallet aloft above his instrument. This moment is full of expectation, of anticipation for the sound that will follow.
In this scene the conductor is using silence to articulate and emphasise the start of the piece. He is making the audience wait so that when the sounds do emerge they will appreciate them more.
We can use silence in exactly the same way, to emphasise sounds at any point within a composition. The absence of sound, therefore, becomes just as important as the sounding objects within a piece.
The composer Claude Debussy believed strongly in the power of silence and once wrote "Music is the space between the notes".

How is the emphasis different between these two sound files?
Silence in Composition
Often, if composers feel that their piece is not quite right, they rush in to add more and more sounds. When really it is just as likely that their piece might require fewer sounds and more silence. Sometimes taking sounds away can be a better compositional choice.
Silence gives the audience a chance to pause, absorb what has come before and to prepare for the next sounds.
Try creating gaps and using silence as a compositional tool in your own pieces.
Identify key sounds within your piece and emphasise them by inserting silence, either before or after them.
Does Silence Even Exist?
John Cage recognised that there was no such thing as complete silence in the real world. Even if you don't make a sound there will still be the whirr of the computer and noises from outside. Cage's piece 4'33″ used this fact to its advantage, encouraging people to listen to the sounds outside of the performer, highlighting the everyday sounds of the audience as compositional material.
