The Japanese have a genius for dreaming up small, useful and fun machines. You must have used or at least heard of Sony’s walkman, Nintendo or Sega’s video games, and Bandai’s Tamagotchi. And how about karaoke, invented by Daisuke Inoue?
Daisuke, who? Not many people have heard of him, and he never made much money from his invention. But anyone who has ever experienced the thrill of singing karaoke in front of a crowd has Mr.Inoue to thank…
Daisuke Inoue is an easygoing man with a quick smile. He was born in the suburbs of Osaka in 1940. At Osaka Technical High School he took up the drums, because he says, “All you have to do is hit them.” Before long he was making money as a drummer in a Hawaiian band that played in the old dance-halls left behind by American soldiers.
By 1970, he and six partners were playing in the clubs of nearby Kobe, acpanying middle-aged businessmen who wanted to sing traditional Japanese country and even army songs. His friends, Inous says, could all read music and so they could pick up the latest tunes (曲调). He, on the other hand, had to rely on memory and play by following the lips of the singer as they moved. “Out of 108 club musicians in Kobe,” he says. “I was the worst! And the clients (顾客) in my club were the worst singers!”
One client, president of a small steel pany, was especially fond of Inoue’s slow, follow-along style. It made the president’s bad, out-of–time singing sound much better. One evening he wanted Inoue to play for him on a trip to a hot spring resort (胜地). The boss wanted to sing Frank Nagai’s Leaving Haneda Airport on a 7:50 Flight for his friends. But Inoue was unable to leave his job.
To help out his most loyal client, he decided to provide him with a tape. Inoue wouldn’t be there, but the singer would still have his acpaniment. Karaoke was born.
