Daughter of the composer, music teacher and organist Rossend Aymí Escolà, Cecília began her studies at the Professional Music Conservatory in Tarragona at a young age where she obtained her first qualification in music, specializing in singing, with the mezzosoprano Mercè Obiol and the repertoire pianist Alan Branch. She went on to obtain her degree in singing at the Liceu Higher Conservatory of Music in Barcelona with top grades where she was taught by Enriqueta Tarrés. Following on from her higher-level studies, she was awarded a grant by the private Duran Martí Foundation to continue studying singing in Munich, Germany.

Throughout her professional career, Cecilia has performed in many internationally renowned theatres and concert halls such as: the Liceu Theatre, Palau de la Música concert hall, and Auditorium in Barcelona; the Fortuny Theatre in Reus; the Faràndula Theatre in Sabadell; and the Wiener Saal concert hall and the Schloss Mirabell venue in Salzburg.

In 2022 Cecilia obtained her master’s degree in Performing Early Music at the ESMUC music school. She is also a founder of the ARTS Performing Arts School in Tortosa and is currently giving singing and choir lessons here at ARTS and also at the Tarragona Council Music School and Conservatory in Tortosa.
