Lionel Tan, founding member of Singapore’s T’ang Quartet and former violist with the Singapore Symphony Orchestra, died on May 31, 2026, at age 60 after a long illness [1, 2]. He had been diagnosed with Stage 4 oesophageal cancer in early 2025 and succumbed to a lung infection following about a month of fighting it, passing away on Vesak Day, according to his brother Leslie Tan [2, 1].

Tan was survived by his partner Marcia Tan, brothers Leslie and Leroy, and his parents [2]. Marcia said, "He put up a good fight for a year and half and I’m blessed to be part of that journey with him" [2]. Leslie described Lionel as considerate even near the end, noting he told family not to fuss and to take care of their mother [1].

The T’ang Quartet announced Lionel’s death publicly on June 1 through a Facebook post, thanking him for his role in the group and saying, "You have fought a good fight, rest well..." [1]. Leslie reflected on his brother’s legacy, noting, "When we were younger, I always looked up to him... Lionel led – I was always a step or two behind. Tonight, Lionel beat me to it again. He should not have departed before me, but he did" [1].

The T’ang Quartet was formed in 1992 by Lionel Tan, his brother Leslie, and violinists Ang Chek Meng and Ng Yu-Ying, all of whom first met in the 1980s through the Singapore Youth Orchestra [1, 2]. The group’s name alludes to China’s Tang dynasty and is a play on the founding members’ surnames: Tan, Ang, and Ng [2].

The Tan brothers left the quartet shortly before its 30th anniversary in 2022. They were succeeded by violinists Han Oh and Wang Zihao, who joined in 2020 and 2021 respectively [1].

Lionel studied at the Royal College of Music in London, where he won the Lionel Tertis prize for viola performance. He was well known for his professional career with the Singapore Symphony Orchestra [2].

Lionel Tan’s death marks the loss of a prominent figure in Singapore’s classical music scene. The T’ang Quartet’s tribute and the reflections of family underscore his impact. His death was formally announced by the quartet on June 1, one day after he passed away [1, 2].
