P237 Monsoon with steel frame

The only one of its kind in the world

In collaboration with universities, scientific institutions, master blacksmiths’ workshops and under the direction of our development team, the Monsoon grand saw the light of day. We have replaced its iron frame with a steel one, which we carved, drilled and milled to perfection so as to preserve both the artistic appearance of a grand piano and above all its romantic tone, characteristic of all PETROF pianos.
