Answer:
An interpretation is an act of explaining or showing your understanding of something.
Step-by-step explanation:
First of all, interpretation requires that you understand the piece of music, text, language, or idea, and also give your explanation of it.
For example, a person who translates one language into another is called an interpreter because he/she is explaining what another person is saying to someone who can't understand. Another example would be how a computer produces masses of data, but it will need your interpretation of the data to let people understand it.
