While the shawm and bombarde band had the advantage of adhering to the Medieval concept of the 'pure consort' (having all the instruments be from the same family), the bombarde was a less-than-perfect bass. For one thing, it didn't have a very low range, with which the introduction of polyphony became a serious handicap. It was natural, with trumpets ubiquitously in the background (both slide trumpets, which are like small trombones, and the natural trumpets that comprise the trombetti) that a slide trumpet might periodically be added to the ensemble. As the slide trumpet was deepened into the Renaissance trombone, it overtook the ponderous bombarde as the low voice in the pifarri ensemble. This shawm and trombone ensemble is the result!
This is really a dance band, in many ways. The ensemble would definitely be classified as loud, and probably did many of the same things that the first pifarri ensemble did. This ensemble remained popular in France, Germany and England long after they died out in Italy. This is due, in great part, to an Italian distaste for dance music (the ensemble's primary function) during the last half of the seventeenth century.
