Included in the first volume of Les Contemporaines (Contemporary Composers / 4 volumes in total), a collection for beginner to intermediate learners supervised by Lucette Descaves. Descaves was a pianist particularly adept at contemporary music, but she was also highly regarded as an educator, and her piano class at the Paris Conservatoire was known for producing many talented individuals. It can be said that such an ambitious publishing project was realized thanks to Descaves' extensive network and exceptional teaching ability. While collections of this kind from France, such as Lemoine's Jardin d’Enfants and Cahier de Lemoine, are popular in Japan, we should re-emphasize the educational practicality and high artistic value of this collection, which gathers high-quality works by over 60 leading contemporary composers across its four volumes.

Pascal contributed the final movement from his piano suite Jardin zoologique (Zoological Garden, unpublished), written in December 1949. This suite consists of five short pieces (Giraffe, Elephant, Hippopotamus, Guard, and Lions, Tigers, and Other Masters), but the title of the final movement was changed for this publication. The original title before the change can also be helpful in understanding the musical character: Mouvement de Marche (In the style of a march movement). It is in 4/4 time and E-flat major. A whimsical fanfare announces the opening, as various animals, large and small, led by the king of beasts, the lion, parade boisterously. The brief roar of the lion king heard in the bass is a charming touch, reminiscent of Saint-Saëns' Carnival of the Animals. The grade is approximately late Burgmüller. Daniel-Lesur, in the preface to the collection, introduced this piece by saying, "One can hear all the inhabitants of the circus (the quadrupeds) parading. If you pay attention to the left-hand movement, you will see the animals passing by. It is a delightful piece."
