Detailed Description

The Master Series – The Acme Of Our Craft

The instruments in this series display the meticulous manual work of our highly experienced master pianomakers. An instrument of this sort normally takes 9-12 months to build and bears the names of the skilled pianomakers, the intoners and the tuners as well as the good name of the entire Petrof family. Pianos of the Master series are intended for use by professionals and in concert halls, where their romantic, soft and unusually rich tone tone will resound to best advantage. Dozens of experienced pianists, with their knowledge and close scrutiny, have contributed to the development of every instrument, and helped us to achieve even greater perfection.


Petrof is currently the largest producer of acoustic grand and upright pianos in Europe. It trades in 5 continents and exports to over 65 countries the world over. Since 1864, when Antonín Petrof built his first piano, they have produced under the PETROF name roughly 630,000 instruments and many others within the PETROF Brand Family. Their pianos are popular among musicians above all for their unusually soft, gentle, rounded and romantic tone. Over the decades of their production much has changed, but precise work by hand, careful selection of materials and the unchanging romantic sound endure. Countless famous performers and well-known personalities have fallen in love with PETROF instruments, and the representatives of the fifth generation proudly continue in their honorable trade and family tradition.

European Excellence

Today the whole musical world knows the top quality instruments from the Hradec Králové factory. For this very reason, PETROF has gained a host of awards – from the King George Medal of the London Exhibition, through the Grand Prix of Paris, Barcelona, and Brussels, to the title „Family Silver“, and Czech Goodwill 2015. All instruments are also marked with the seal of European Excellence, which attests the European origin and the quality of the construction materials.

Available With The Pianoforce Performance Self Player System

This new generation of the Pianoforce Performance Player system is compact and elegant, and it suits any kind of grand piano. Advantages of the system are an easy control, the ability to play the music from different resources, the possibility to store the music on the device’s internal memory, a simple handing, and wireless internet connection. The system can be handled with ease via your mobile phone using Wi-Fi. The Pianoforce Performance Player system is installed with sound speakers allowing you to enjoy your performance with a background.

The sound is formed mechanically, the same way a proper grand piano works during a performance, by hammers striking the strings. The composition is reproduced in a form of digital data. Dynamics are included, thanks to the electromagnets, which transfer the movement to the keyboard and to the action. The grand piano reproduces a realistic performance by hammers striking the strings and soundboard resonating. The result is indistinguishable from a living artist performance.

Supported media: • 500 performances in the memory included • CD and USB are supported • Multiple internet stores purchase of additional performances • PIANOFORCE RADIO – non-stop performance via internet radio (for a one-off fee).

The self player system is an optional add-on to all Petrof grand pianos.
