This study explores the role of musical salons in nineteenth-century Mexico as dynamic spaces where gender, sociability, and national identity intersected. Salons functioned as transitional domestic arenas where elite women played a central role in music making, shaping both cultural tastes and national sentiment. While largely absent from traditional music histories, these spaces were crucial to the circulation and performance of European and Mexican music, fostering artistic exchange among amateurs and professionals. Through tertulias (soirées), women exercised agency in defining musical and social conventions despite being constrained by patriarchal norms. Drawing on historical accounts, literary sources, and travelers’ testimonies, this work highlights the importance of salons as sites of gendered musical practice, elite cosmopolitanism, and identity formation in post-independence Mexico. It also underscores the need for a revised historiographical approach that integrates women’s contributions to the broader narrative of Latin American music history.
