Can you explain what transpose means in terms of music theory?

Transpose is a musical term that refers to shifting a musical passage or part up or down in pitch by a set interval. This is commonly done with the melody of a song, for example, raising it a fifth, but it can also be done with the key of a song. Transposing can be helpful when trying to find the best range for a particular singer, or to make a song fit with a certain instrument's range, or to provide a better harmony to a particular part.
