Singing has always been in the blood of Samuel Yuen Hao.  He started performing on stage during his kindergarten graduation concert, and he was invited to join his school choir early at primary 2, while most other boys would start in primary 3.  At the age of nine years, he started voice lessons with Ms Khor Ai Ming. In 2018, he obtained the Associate Trinity College of London (ATCL) Diploma.

Apart from the regular performances with Vocal Associates, he has performed in numerous events, both locally and overseas, either as a soloist or as part of a choir.  More notably, are his role as boy soprano in the opening number of the Chingay Parade 2013, “Fellowship of the Ring” and “Two Towers” movie concerts with the Metropolitan Festival Orchestra, “SSO Christmas Concert” with the Singapore Symphony Orchestra, “The Planets” with Orchestra of the Music Makers, “Winds of the East” with Singapore Wind Symphony, “Faure’s Requiem” with Braddell Heights Symphony Orchestra, “ChildAid Concert All Stars 2014”, and performing as a winner in New York Carnegie Hall for American Protégé International Vocal Competition. In July 2017, he appeared with the Honors Performance Series Choir at the Sydney Opera House.

Samuel also actively participates in community outreach activities. He performed for the PAssionARTS Singing Festival, which took place at various locations such as Bukit Merah, Toa Payoh, Bedok Town Centre, Bedok Library and Nee Soon Market. As a part of the Music Elective Scholarship, he also had the opportunity to mentor students from Queensway Secondary School. During his school’s Values In Action project, he was involved in teaching music to kids at Children’s Wishing Well, a non-profit organisation caring for children in low-income households. Samuel has also been involved in teaching music to children with special needs, such as students with visual-impairment and autism. He has also been involved in projects with Purple Symphony, which promotes inclusivity by including people with and without special needs.
