Yunchan Lim restores the improvisatory impulse to Carnegie Hall

Yunchan Lim’s Carnegie Hall debut confirms that the pianist is a primary agent of a return to the improvisatory impulse. His Mozart—specifically the Piano Sonata No. 13, K.333—is a rejection of the metronomic, competition-ready performance standard. Lim employs a degree of rubato (the flexible stretching or contracting of tempo for expressive purposes) that borders on the transgressive in a modern context. Where his contemporaries prioritize the clinical precision demanded by recording studios, Lim prioritizes the volatility of the live event. This is a recovery of the 18th-century stylus phantasticus (a free and unrestrained style of composition) applied to the Classical canon. The risk-reward ratio of his playing suggests an artist who views the score as a map rather than a cage.
