MORE than 350 young pianists from 24 schools played non-stop for 30 hours at Ocean Terminal, Cityplaza and Whampoa Garden on Mother's Day to raise $300,000 for Oxfam Hongkong's development projects in Asia. The theme for this year's pianothon is ''Music For Development: A Mother's Day Celebration'' and the students invited their parents to attend as a special Mother's Day treat. According to Mr Stephen Tsui, Community Relations Officer of Oxfam Hongkong, this was the third year they had held the pianothon, but the first time it was held on Mother's day. ''In the past two years, parents of the young pianists were excited and enthusiastic. They brought their camera recorders to record their children's performance. So, we decided to hold the event on Mother's Day as a tribute to the parents,'' Mr Tsui said. The gala attracted about 200 people to the Ocean Terminal performing platform where the young pianists displayed their musical talent. Participating schools were divided into teams and each team played for one hour or more. A sponsorship target of $10,000 was set for each team. The age of the young pianists ranged from four to 18. The youngest of them, Dawn Moakes, became the centre of attraction. Accompanied by her mother Miranda Moakes, Dawn played ''Mary Had a Little Lamb'' and ''Carry Me Back to Old Virginia''. Dawn, who goes to Tinkerbell Kindergarten, has learned to play the piano for three months. She spent three weeks practising for the performance. Even though Dawn is only four, she was not shy to perform in front of the large audience. Asked if she wanted to be a pianist, Dawn gave a lovely smile and nodded. She raised $2,670 from friends and relatives. Oxfam Hongkong also staged a photo exhibition on women in Third World countries. Renowned pianists Choy Sown Le and Nancy Loo also attended the event. Choy gave a sparkling performance while Loo gave a speech to encourage the audience to spread the message of love and care through the piano. A group of students from South Island School sang ''Think of Them'' which was specially written for Oxfam by their music teacher Ian Williams.
