G'day John,
could this: "Bach, Johann Sebastian: 2-part inventions No. 4 in Dmi Clavier" be what you're looking for?
A wonderful resource for identifying themes is: http://www.musipedia.org/
You use an approach called "Melodic Contour" or "Parsons Code". It is explained on the site and has remarkable accuracy.
