The orchestra at the Bouffes-Parisiens was small – probably about thirty players. The 1858 version of "Orphée aux enfers" is scored for two flutes (the second doubling piccolo), one oboe, two clarinets, one bassoon, two horns, two cornets, one trombone, timpani, percussion (bass drum/cymbals, triangle), and strings. The Offenbach scholar Jean-Christophe Keck speculates that the string sections consisted of at most six first violins, four second violins, three violas, four cellos, and one double bass. The 1874 score calls for considerably greater orchestral forces: Offenbach added additional parts for woodwind, brass and percussion sections. For the premiere of the revised version he engaged an orchestra of sixty players, as well as a military band of a further forty players for the procession of the gods from Olympus at the end of the second act.
