This is the first part of a tune called Krebbel in Belgium, although it may have older eastern European or Gypsy roots. The low A at the end of the B part, which notably has only 7 bars, is almost certainly intended to be the growling of the bear. Locally, this tune is played before Bear Dance #2, but elsewhere the order is sometimes reversed. Some local groups play a different subset, consisting of the A part of Bear Dance #2 followed the A part of Bear Dance #1. There is also a third Bear Dance that serves as an introduction and tag ending, and many other similar versions of part of all of these tunes.

This very possibly ancient tune is from Brittany, where it is named Dans En Dro after a type of dance that originated in the city of Vannes, located in the southern part of Lower Brittany.
