Licensing
This is a sound sample from a commercial recording. Its inclusion here is claimed as fair use because: I believe that this use of the excerpt is in good faith, and that its inclusion enhances rather than reduces the commercial value of the recording from which it was drawn; however, if the owner of the copyright wishes to challenge my use, I will be happy to remove it promptly, with apology.
 * it illustrates an educational article that includes a historical and critical examination of the excerpt;
 * it is a sample of about 13 seconds from a much longer recording, and could not be used as a substitute for the original commercial recording; and
 * it is not replaceable with an uncopyrighted or freely copyrighted sample of comparable educational value.
