Although J.-Ch. Hess wrote a number of works for organ and
harmonium, which would reflect his profession as church organist, the main body of his music consists of light
salon music for the piano. This in itself can be divided into original compositions and arrangements of popular melodies and arias from contemporary operas, the latter often in the form of a
fantasia or of a
theme and variations approach. Hess was a particularly prolific composer: the catalogue of his published compositions in the
Bibliothèque nationale de France numbers more than 370. Some of these pieces were eminently successful. In an obituary notice, the French journal
Le Ménestrel – like most of Hess' music published by
Heugel – wrote "They were truly popular and their print runs reached hundreds of thousands of copies" ("[Ils] furent véritablement populaires et leurs tirages montèrent à des centaines de mille d’exemplaires"). Among his most popular pieces were
Où vas-tu, petit oiseau?, Op. 17 (1853, on a popular song by
Léopold Amat), his fantasia
Le Carnaval de Venise, Op. 43 (1857, on
André Campra's opera of the same title), and
Le Cor des Alpes, Op. 59 (1860, on a piece of the same title by
Heinrich Proch). ==Selected compositions==
