Sydney was born in Paris into a family of artists. She grew up surrounded by writers, painters, and musicians. She recalls always having a keyboard nearby from her earliest memories.
 
Sydney began her journey as a professional pianist as a teenager under the guidance of the Russian concertist Elena Varvarova. She then met Professor Francis Vidil, whose influence became a pivotal point in her career when, through research and her keen interest in historical pianos and period instruments, she discovered her passion for musical interpretation in a historical context. 
 
Sydney studied at Paris Conservatoire (CRR), Versailles Conservatoire, Aubervilliers Conservatoire and the Catholic Institute of Paris. She holds three performance degrees (piano, pianoforte, piano accompaniment) and three academic degrees (French literature, music history, music theory). She then specialised in Early Music at the Royal Conservatory of the Hague (Netherlands). Since 2010, she has been teaching piano and music theory in music schools and Conservatories, while also pursuing a career as a performer and musicologist.  
 
As a teacher, her main goal is to help students express themselves by giving them as many interpretation tools as possible so they can develop their own musical personality.  She likes to broaden her students’ horizons by suggesting new and interesting repertoires. She loves to share her passion for historical musical performance by introducing them to early music, basso continuo, improvisation, accompaniment, romantic music or how to read a set of chords with a jazz notation. 
 
Her main areas of interest as a pianist and researcher are late eighteenth and early nineteenth-century repertoire. She has a passion for historical reenactment, making her own costumes of the period, while showing connections between folk and classical music, enjoying the discourse between music and literature.
