Members of the junior Hong Kong Chinese Orchestra gave a demonstration yesterday in the hope of attracting support for an attempted double record-breaking drumming session on July 13. Two thousand drummers will strike a drum measuring 2.6 metres high and 3.46 metres wide. It is hoped that the session will earn entries in Guinness World Records for the most number of drummers and the biggest drum. The instrument is being made in Shenzhen and will be played in Victoria Park to start the Hong Kong Drum Festival. The drum is due to arrive in Hong Kong by sea on July 11 or 12. 'First, we had to find an ox big enough to provide the skin,' said Yim Hok-man, the orchestra's deputy concert master. 'Then we had to think about transport. 'Trucks carried the raw materials from Shanxi to Shenzhen so that once the instrument had been made it would be closer to Hong Kong.' On the big day, one of the youngest drummers will be six-year-old Fifi Wong Ga-ting, who has been playing the instrument only for a few months. 'I am very excited because it will be so grand,' she said. Another eager drummer is Chan Sze-sze, nine, a Primary Three student at a Kowloon Tong school. 'I am not nervous,' she said when asked about the record-breaking challenge. At present, the largest drum is Ireland's Millennium drum with a diameter of 4.72 metres and 1.01 metres deep.
