Those who enjoyed the National Day celebration fireworks will be treated to two more large-scale shows during the Hong Kong International Musical Fireworks Competition. Teams from Hong Kong, Italy, Japan and the United States will vie to outdo each other in exhibitions that will be synchronised to music. Hong Kong will compete against Italy tomorrow at 8pm. A week later Japan will take on the United States. The teams will be judged on the quality of the fireworks, their synchronisation with the music, the pyro-musical design and general crowd appreciation. Jeff Lui, of Hong Kong's team, said its display would have an 'east-meets-west' theme that would comprise 'a fusion of Chinese and Western folk songs'. The Americans' display will be the premiere of the 'Art of Fireworks Digital Choreography', in which fireworks will be 'perfectly synchronised to the music with the help of a special virtual fireworks simulator', according to team member Kevin Kelley. 'Using our software, we are able to produce three-dimensional images allowing us to look at a virtual show from all directions,' he said. 'We know exactly how the show will look. The only thing we can't control is the weather.' The US team's performance will use music made famous by cowboy and western films of the 1950s and 60s - themes from The Magnificent Seven and How the West was Won. Japan's theme will be 'Four Seasons'. It, too, relies on assistance from computer effects and will be accompanied by Japanese music. Not surprisingly, the Italians are drawing on their nation's rich history of classical music for inspiration. Their 'Opera Classic' will see fireworks combined with masterpieces by Rossini and Verdi and will make use of a recording of the Three Tenors singing La Traviata. Unlike the Americans and Japanese, however, the Italians will perform without the help of computers, according to team member Pierpaolo Serafino. The amount of firework shells used in the competition will vary among the teams, though at a lucky 8,800, the count from Hong Kong's team is the highest. But sheer volume will not win the competition. Wilson Mao, the technical consultant for the competition, stressed that the quantity of fireworks was not important when compared to the 'design and effect' of the exhibitions. All the teams declined to reveal how much they had spent preparing for the event. Each team expressed gratitude at being able to take part in the event, with competitors praising Victoria Harbour as 'the most beautiful harbour in the world'. Vantage points from which to view the fireworks are along the waterfronts of Tsim Sha Tsui, Central, Admiralty, Wan Chai, Hunghom and the Hunghom Bypass. Special traffic arrangements along the vantage points will be in place on the days of the performances.
