Pascal's first published collection of piano pieces for learners. It bears the subtitle "12 Easy Exercise Pieces" (12 morceaux - exercices assez faciles). Even at a time when he was regarded as a rising conservative composer, his style was unpretentious, featuring neatly crafted pieces. While the main technical focus is indicated in parentheses next to each piece's title, they avoid a rigid etude-like character, brimming with playfulness throughout. Despite the limited number of notes, they incorporate a modern twist of difficulty. They feel like a slightly simpler and more concise version of Debussy's "Children's Corner". It is recommended to approach these pieces after progressing through Czerny's Op. 299 (School of Velocity). This collection was widely popular in France, with the second and twelfth pieces sold separately as individual sheets.
