Described by Alina Ibragimova as "a wonderfully dedicated group of musicians who bring assuredness and freshness to everything they play", the Kleio Quartet was formed at the Seiji Ozawa International Chamber Academy in 2019. They consist of individually acclaimed musicians Yume Fujise, Katherine Yoon, Jenny Lewisohn and Hsing-Han Tsai.


They have performed in major international venues such as the Wigmore Hall, Victoria Hall, Cadogan Hall, Royal Festival Hall, the DR Koncerthuset and many others.

The Kleio Quartet is particularly grateful to have received support and mentorship from Alina Ibragimova, as well as from John Myerscough thanks to ChamberStudio's Mentorship Scheme. They have also received coachings from world-renowned chamber musicians Sadao Harada, Nobuko Imai, Pamela Frank, Pinchas Zukerman, Michael Gurevich and Pablo Hernán Benedí.


This season they will hold a Residency at Snape Maltings' Britten-Pears Festival in Aldeburgh.
