His work is characterized by melodic richness and lyrical charm, often reflecting the styles of the Belle Époque. One of Brehy’s notable works includes the operetta "La Veuve joyeuse" (The Merry Widow), which showcased his ability to blend humor with romantic themes. Though he may not be as widely recognized as contemporaries like André Messager or Franz Lehár, Brehy's music contributed to the evolving landscape of French light opera during this period, helping to cement the operetta's popularity in France and beyond. Brehy's impact on music lies in his role in popularizing the operetta form, which influenced later composers and the development of musical theatre. His works often celebrated the joyous and whimsical aspects of life, resonating with audiences and reflecting the cultural zeitgeist of his time. Despite the passage of time, Brehy’s contributions remain a noteworthy part of the operatic tradition in France.
