Lyda Chen-Argerich is a Swiss-born lawyer and musician (violist), the daughter of two prominent musicians: Martha Argerich, an Argentine pianist, and Chen Liang Sheng ,^[1] a Sino-Swiss conductor. She has excelled as a performer of classical music for Viola, although she initially studied and practiced the violin.^[2]

Born in Geneva, Lyda Chen-Argerich is one of the three daughters, the eldest, of Martha Argerich. She studied law in Geneva and simultaneously studied violin at the Geneva Conservatory with Ayla Erduranand and later at the Central Conservatory in Beijing, China, with Lin Yao Ji. She is also the daughter of another famous in the musical world, known to some as Robert Chen (Chen Liang Sheng: 陳亮聲, 陈亮声, pinyin), a Chinese-Swiss choir and orchestra conductor.

Lyda has two half-sisters, daughters also of her mother.

The younger Stephanie Kovacevich, filmmaker and daughter of American classical pianist and conductor Stephen Kovacevich, presented at the 2017 Rome International Film Festival her debut feature Bloody Daughter,^[3] a documentary that chronicles the three daughters' intricate relationship with their mother. Particularly, referring to sister Lyda, said one film critic "her story would merit a film by itself." The other of Lyda's sisters is Annie Dutoit, daughter of another famed conductor and also a violist, Charles Dutoit.^[4]

Although the violin was the first instrument Lyda Chen played, she soon opted for the viola, on which she perfected her skills with Gad Levertof, a professor at Tel Aviv University. Lyda first came to her mother's country, Argentina, on her eighteenth birthday, when she visited her maternal grandparents.^[5]

She has recorded works with her mother Martha Argerich, among others the Piano Quartet in E flat by Robert Schumann and quintets by Shostakovich.

At the Lugano Festival they recorded Beethoven's Quartet in D major No.
