Following the public success of the first set of Petites Pièces arranged from Mozart, the Leipzig publishers Peters issued a second collection in 1804 drawing on the little-known repertoire of basset-horn trios and horn duos; three extracts from the choruses of Le Nozze di Figaro would have been the only material familiar to the general public.All the pieces were arranged with a clear eye to the amateur market with no great technical demands or wide stretches, and where Mozart had left few dynamic markings, the arranger carefully marked suitable and stylish expressive effects. This repertoire would be effective today on the modern piano, the fortepiano or the clavichord.
