He gave recitals, but also wrote compositions for piano, including Soirée d'amour (1895), Quintette des fleurs (1896), Mandolines à la Passante and Cinq Fantaisies, and a Concerto (1898) and a Konzertstück for piano and orchestra.

In 1896 Delafosse gave a series of concerts in London with the famous Belgian violinist Eugène Ysaÿe to a mixed reception.
