Fortunato Chelleri (1690 -1757) was an Italian Baroque composer. From his hand is a small bundle of 6 Fughe per il organo, composed around 1725.The fifth of these fugues is actually not a fugue at all. It is more like one of the two part inventions of J. S.Bach. And a good one too! Full of wit and energy this fifth fugue is a joy to play.
