His previous work, Préludes flasques (pour un chien), was rejected by Durand publishing house. One month later, he composed this three-movement piece, adding '(véritables)' to the title.

First Movement: Sévère réprimande

The first movement, titled 'Sévère réprimande' (Severe Reprimand), is written in a toccata-like style. It seems to incorporate Baroque elements. The right hand consists of continuous groups of four eighth notes, while the left hand's bass part is formed by long note values, reminiscent of organ sonorities. The bass seems to support the intricate movements of the right hand. This movement includes performance indications such as 'Donnez, de même, persuadez, mouillez, charnu, cérémonieux, comme un éducateur'.

Second Movement: Seul à la maison

The second movement, titled 'Seul à la maison' (Alone at Home), features continuous groups of six eighth notes in the left hand, with a melancholic melody in the right hand. The occasional rests in the right hand further emphasize the sense of solitary space. It is written in a two-part contrapuntal style. Unlike the first movement, it has an introspective atmosphere. Performance indications in this movement include 'Plus clair, substantiellement, avec précaution'.

Third Movement: Un jeu

The third movement, titled 'Un jeu' (A Game), is written with the right hand in a continuous succession of fifth and fourth progressions. The style of writing might be based on the bourrée, a 17th-century French dance. Performance indications in this movement include 'Un peu, voilé, d'imitation, inattendu, séparé'.

While 1912 is considered his 'humorous period' in terms of his creative style, this work fuses elements from his earlier period, which incorporated Baroque styles.
