Description
The ANT. PETROF 136 is potentially a revolutionary instrument in the history of piano manufacture. Write history with us and allow yourself to be carried away by its grandiose yet unusually pleasing tone.
The ANT. PETROF 136 upright is the youngest family member. The original and unusually robust construction of the body gives the piano great solidity and guarantees the long-term stability of the instrument, especially in its tuning and action. These attributes are essential for achieving high quality performance., and contribute greatly to a player’s confidence. Its high acoustic capacity, the response of its action, its colourfulness across the whole tonal range and its characteristic romantic sound makes the piano similar in feel to a concert grand.
