David Klavins is a pianist who, for years, could not find pianos that made the sounds he imagined in his head. So he began building pianos to his own specifications in a workshop in Vác, Hungary, and they are truly unique creations. To wit: Klavins’ vertical concert grand stands over 15-feet tall, and he actually has to climb a ladder to play it, which he does, beautifully, just for us.

I love the sound of the big one!

They were all reminiscent of a harp to me?

I thought that of the second one he played on. All three instruments had a great sound of their own, I think. The big one just was my favourite, full and soft at the same time.

Agreed (but you’d need a large room)!
