When Ariadna Padron Yassin sang at ChildAid 2011 as a nine-year-old, she was a bundle of nerves.
"I was very nervous. I was shaking," says Ariadna, now 11, on taking to the stage then for the charity concert.
That experience helped her overcome stage fright and become more confident, she adds. It also gave her a taste of what it means to be a professional performer. "I learnt about being backstage, how you are supposed to behave.
"You must be disciplined, come on time, listen to the stage manager," she adds.
The New Town Primary School Primary 5 pupil now aims to get into the School of the Arts to pursue theatre or music. She is also back to showcase her vocals for this year's edition of the annual charity concert on Dec 6 and 7.
Intensive rehearsals started on Tuesday at the Singapore Press Holdings' Media Centre in Genting Lane. Ariadna and four other young female vocalists have been practising a medley of Somewhere Over The Rainbow, It's A Small World and Lollipop.
While the children take singing their own parts seriously, they also enjoy light-hearted moments during rehearsals. At times, two of the youngest vocalists - Anne-Sophie Cazaubon, six, and Akira McLatchie, seven - bopped to the background music, jumping up from their seats and breaking into an impromptu dance.
The cast of 130 performers for the carnival-themed concert - featuring aerial acrobats, gymnasts, musicians, vocalists - will be backed by a 33-piece orchestra.
