Grand Piano Petrof Special Collection Gravelli

When the idea of producing a fully functional concrete piano was born, it was clear to everyone that it was a big challenge.
The main parts are made of a specially developed concrete mixture by Gravelli which is reinforced with tiny glass fibers.
Steel has been chosen as the most suitable material for the base, matching concrete perfectly.
It is a modern material concept of a classical piano, which is designed especially for the admirers of minimalism and contemporary architecture.
