The Vancouver Symphony will open its 38th season with an all-Russian program that will feature acclaimed Japanese violinist Mayuko Kamio playing Tchaikovsky’s Violin Concerto, one of the most beloved in the repertoire.Kamio, 30, has won a number of violin competitions, including the gold medal of the 2007 International Tchaikovsky Competition. Yes, that’s the same competition that Van Cliburn won in 1958 at age 23. So when you do the math, you’ll realize that Kamio won it when she was just 21.Like other prodigies, Kamio started early with music lessons, but hers had a slight twist. She began with the piano when she was 3 years old but didn’t take to it.“I totally disliked playing the piano,” Kamio said. “So my grandfather suggested that I should try out the violin instead, and on the day I received my first violin, I made a stage myself with a table and pillows, and made everyone listen to me all day. I was 4 years old.”Kamio became so accomplished with the violin that she debuted as a soloist in Tokyo at age 10 under the baton of Charles Dutoit in a concert that was broadcast on television. But she takes nothing for granted and still practices about three hours a day. She first performed the Tchaikovsky Violin Concerto when she was 12 years old. Since then, she has performed the concerto in public almost 80 times.
