The use of music
Explanation:
<em>The independent variable in the example is the use of music.</em>
The independent variable in research or experiment is a variable whose value is not affected by any other variable. That is, the value of an independent variable is not influenced by any other variable.
<u>In this case, the use of music stands alone and is not influenced by any other variable in the experiment. In actual fact, the use of music's effect is being tested in the experiment and hence, is not in itself influenced by any other variable.</u>
