He's the mastermind behind some truly unconventional pianos like this vertical concert grand, the tallest piano in the world.

We met David in a small town in Hungary when we made a short film about him.

Today he invites us to his workshop where we can sit back and enjoy the sound of each one of his unique pianos.

Okay, come with this is the concert on accord up on one accord comes from the fact that it only has one string per note.

It's like 2 m tall and 2 m 20 wide.

Yeah, this is one of my pianos, the accord up.

But the character is generally softer.

Each note in itself is always clear.

It cannot be out of tune.

Yeah.

Yeah.

Okay.

This is my biggest piano, the vertical concert grand of 4 m 70.

The concert pianos double strings from the first base note, which no other piano has makes it the fullest sounding piano on the planet.

Yeah, so Mm.

Mhm.

My main motivation to create the pianos that we built today was that I had an imagination of sound that didn't exist, as I found out in the course of my life, working with pianists, they are also not satisfied with traditional pianos.

Essentially, I love to provide people tools to create new and beautiful music.

The world needs different sounds better.

Sounds more sounds in the piano field.

Yeah.

Mm.
