Mô tả

Its tremendous sound reaches into every corner of any concert hall in the world. At the same time it remains true to its roots and respects the colourful, romantic and rounded tone of PETROF instruments.
It may be a giant, but its elegance and sensitivity are remarkable. An instrument that breathes life into the wildest dreams of the artistic spirit, while opening the hearts of the most demanding listeners
The ANT. PETROF 275 was the first instrument of its name, and is the PETROF company flagship. The eyes of the world watched over its five years of development and two years of testing.
This instrument brought many innovations to the pianomaking craft, some of which have since been patented, and it has come to symbolise modern technologies while at the same time preserving the traditional techniques of the greatest pianomaking craftsmen. In particular its completely new construction, first class materials and careful processing make it an impressive instrument.
