Fair use for Polytonality
The image linked here is claimed to be used under fair use as:
 * 1) it is a small portion of two voice's parts, not the piece;
 * 2) the transcription is only being used for informational purposes;
 * 3) it is inferior to the original piece;
 * 4) Its inclusion in the article adds significantly to the article because it shows a part of the allusion, cryptogram, and quotation techniques used.
