Hong Kong pianist Aristo Sham says winning the Van Cliburn International Piano Competition in the United States was a "surreal" experience that will take time for him to process what the victory truly means to him.

On Saturday, Sham became the first local pianist to win the top classical music contest, which is held once every four years.

Speaking to RTHK, Sham said he's very happy to have represented the SAR in taking home the prize on this important stage.

He thanked his family, friends and teachers for their support and grooming when he grew up in Hong Kong, before he moved to London and the United States for his studies.

The 29-year-old pianist said winning the competition gets him more opportunities to perform.

However, he said, it gets more difficult from here, as he has to become what he called "a genuine artist" through his performances.

Sham said he's always enjoyed self-discovery when young to find out what he loves and values the most.

He has also been through times when he very much questioned himself.

"It was a rather difficult time for us musicians during the pandemic," Sham said.

"For a year I didn't really play the piano – there wasn't much of a chance to perform.

"I had plenty of doubts four, five years ago.

"I think for artists, we all go through different bottlenecks and challenges during our careers.

"But once you get through them, you can make the best works of art."

Sham started playing the piano at the age of three and was perceived as a "piano prodigy" from a tender age.

He didn't feel pressure because of it, noting that those with talent still need to work hard and gain experience to achieve success.

For him, local young musicians should keep loving music and enjoy what it brings to life.
