ANT. PETROF 136 (53.5'')

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.



Renner-ANT. PETROF. For the highest possible action stability, there are four action bracket used in the AP 136


Dense maple wood bridges facilitate excellent transmission of strings vibrations to the soundboard.

Key bed

The solid key bed (45 mm thick) made out of cross laminated birch wood provides structural integrity of the instrument. This ensures longevity to action regulation and accuracy for pianists.


These new ergonomically designed solid brass pedals are made to simulate more of a grand piano feel. They are wider, lower to the ground, and incorporate a fully adjustable wooden mechanism.

Iron plate

Drilling of the cast iron plate on the CNC machine generates an accurate and consistent framework for precision scale design. Exact speaking lengths of the strings result in optimal vibrations which produce a bright, singing tone.

This full surround frame also contains more open areas which enable greater resonance coming from the soundboard.


The newly designed, European solid spruce soundboard provides an incredibly full dynamic range while retaining PETROF’s characteristic romantic tonal color. It is called a “floating” soundboard which contains areas unattached to the frame, freeing the vibration of the board.

Wooden frame

The joint and tenon frame of the AP136 is what you would expect to find on high-grade finished carpentry. While the six solid spruce back posts are carved by computerized lathe (CNC) for precision fit, the frame is completely built by hand.

Cut-off bars

There are two cut of bars used in AP 136 construction

Fallboard damper

This elegant recessed slow-close fallboard system is the same as you would find on a high quality grand piano.



For a professional pianist, making music is both a joy and a responsibility. Pianists hone their minds, hands, and ears not only through extensive training in educational institutions, but over years of practice on a variety of high-end pianos. They train to control the action and to be fluent in the elements of music: tonal color, dynamic range, and stylistic expression. But however skilled the pianist, he or she is only part of the equation. The performance also requires a high-quality piano — one responsive enough to translate the player’s artistry and skill into sound, and able to project that sound to the audience.
