From an interview on the Forbes promo site:
Interviewer: You’ve just pledged $5 million to help kids learn to play the piano. That’s an incredible donation! Why don’t you tell me a bit about it?
Lang Lang: It’s with my foundation, the Lang Lang International Music Foundation. We give $1 million to the American public schools every year from the last three years to the next five years.
IV: So this donation has already commenced.
Lang Lang: Yeah, it’s already started. We are going forward this next year, the next five years, with a $1 million donation. Our aim is to bring music education back to the States, to the public schools in the U.S.
IV: What made this the best time to commit to that?
Lang Lang: Music changed my life and I think there are so many talented students in the U.S. and they need our help to get proper music education. There’s new technology for piano method and music method, so we’re not only doing the hardware, we’re also building the software with the new books with new methods of playing piano, with smart electronic pianos, with very well trained music teachers and great visiting artists from around the world.
