Composed in August 1931 in Willer (Alsace region). The instrumentation indicated on the published score is "for two harpsichords, or harp and piano." On the other hand, Marc Honegger's catalog of Migot's works adds "two harps or two pianos" to the aforementioned instrumentation and places it in the piano duo category. Since Honegger's fundamental policy was consistently to adhere faithfully to Migot's own intentions, this work can be considered almost a legitimate piano duo piece. It is dedicated to the harpsichordist, Pauline Aubert. It was published as a set with "Prélude pour un seul" (for harpsichord or solo piano). "Pour deux" and "Pour un seul" are essentially the same piece; "Pour deux" is arranged for two players to alternate playing "Pour un seul," with one part adding ornamentation. When performing "Pour deux," it is advisable to refer to the score of "Pour un seul" to identify which sections correspond to the essential parts played by "Pour un seul" and which should be regarded as ornamental. It begins in G Mixolydian mode in 6/8 time and concludes on a C major tonic chord. The ancient modes lend a certain archaic charm. The two main musical ideas, "Gracieux et souple" (Graceful and flexible) at the beginning and "Tendre et pathétique" (Tender and pathetic) immediately following, form the core, with subtle tempo fluctuations.

The understated quality, like a gust of wind blowing through, resonates with the refined elegance of French Baroque harpsichord works, which constituted the dedicatee's primary repertoire. In "Pour deux," the addition of diverse ornamentation creates a rich tapestry of sound. The unique distortions and twists created by intricate polyrhythms are outstanding. A fine work possessing a distinct modernity.
