As a composer Samuel-Rousseau was highly influenced by the works of Franck and Fauré. He tended to be more conservative in style than many of contemporaries but he was a master at chromatic harmony and had a strong sense for the dramatic. His compositions include operas, ballets, orchestral and piano music and songs. His best works are his operas, which tend towards the exotic and are ambitious in scale. Two of his operas, Le Hulla (1920) and Kerkeb (1931), are based in the Orient; with the latter's title role a Barber dancer in a harem. His opera Tarass Boulba (1919), is based on the legend of a Cossack warrior. He also wrote one opera based on the Arthurian legend Le roi Arthur (1903).
