Born in Vic (1991), Maria Mauri studied piano and conducting at the Catalonia College of Music (ESMUC). She rounded off her education with studies at the Guildhall School of Music and Drama in London, where she completed a master's degree specialising in collaborative piano. She has studied with professors Vladislav Bronevetszky and Nelly Ben-Or (piano), Johan Duijck and Josep Vila i Casañas (choral conducting), Salvador Brotons (orchestral conducting), and Pamela Lidiard, Andrew West and Francisco Poyato (lied). Mauri has also studied singing, and one of her great passions is vocal music, which has led her to specialise in the vocal and choral repertoire.

She has accompanied a number of Catalan choirs: Cor Madrigal, conducted by Pere Lluís Biosca; the Cor Jove Nacional de Catalunya, with conductors Lluís Vilamajó, Mireia Barrera and Catherine Simonpietri; Cor Bruckner Barcelona, conducted by Júlia Sesé, and Capella Nacional de Catalunya, with musical direction by Lluís Vilamajó and Jordi Savall, among other ensembles. Mauri has also performed in lied and opera recitals with different singers, including Josep-Ramon Olivé, Enric Martinez-Castignani, Núria Vinyals and Kathryn Smith. She has performed at festivals and cinemas throughout Catalonia, as well as in England and France. She has worked at the Liceu Conservatory as a pianist for vocal repertoire.

She has been awarded numerous prizes and scholarships, including from the Fundació Victoria de los Ángeles, the Guildhall Scholarship Awards and the Anna Riera Scholarship, and was involved in recording the album Pau & Victòria.

She currently combines her work as a pianist at the Orfeó Català Cor de Noies, conducted by Buia Reixach, with her projects as a conductor, singer and teacher. Since 2019, Mauri has been a classical piano teacher at the Taller de Músics School for Higher Music Education, as well as head conductor for the chamber choirs Noctes and ARSinNOVA. On the other hand, she sings in several vocal ensembles, focusing mainly on ancient music and contemporary music, including collaborations with Companyia Musical and Marina Herlop.
