Advantages of the construction and materials used in the PETROF P 173 Breeze grand piano



The rim is a Petrof original design.
The inner rim is laminated with 9 sheets of solid beech and birch lamellas and is CNC machined for high accuracy.
The outer rim is sandwiched from solid alder core and outer HDF lamellas with veneer.
The inside facing is veneered horizontally with Ebony Makassar.
The total rim thickness is 5,8 mm.

The solid rim ensures long term tuning stability and action regulation  stability. A firm CNC machined rim supports the proper crown of the sound board, which produces the precious PETROF tone. Rare Ebony wood on the inner face of the rim gives the nogle appearance that is deserving of a PETROF grand piano.

Frame posts

The PETROF frame consists of 3 longitudinal spruce posts.
The joints of the posts and rim are dove tailed (fish tailed) and doweled with beech hardwood dowls. The entire wooden frame is CNC machined to insure an accurate fit to support the crown of the sound board.

The firm frame with solid posts provides a high form stability of the frame, tuning and regulation stability.


The legs are a Petrof original design.
The legs are made with a solid beech core, an outer layer of alder, a Gabon counter veneer, and an outer decorative veneer.
The frong legs are 625 mm in length.

Strong leg construction ensures high piano stability when being played dynamically. The legs are proportioned adequately to the size of piano.

Iron plate

The iron plate is produced in the Czech Republic.
The iron plate is made from grey cast iron, wet sand cast, and hand finished; then it is CNC machined for exact strings length.
Each plate is finished in the new dynamic gold color.

CNC machining ensures high accuracy of string scalling and accurate fit to each piano. Our new plate color enhances the beauty and noble look of the PETROF grand piano.

Hardware fittings

The hardware is a Petrof original design.
The hardware is solid polished brass, lacquered and stain resistant.

The pin block is highly resistant to climatic changes, providing stabe torque of tuning pins and high tuning stability.


The soundboard is a Petrof original design.
The soundboard is made from selected European spruce. It is symmetrically crowned and wedge tapered from 9 mm in front to 7 mm in back arc.

Traditional symmetric crown and wedge tapering of the soundboard gives the piano good acoustic performance in  whole tonal range and induces typical tone of PETROF grand pianos.


The ribs are a Petrof original design.
The ribs are made from selected fine European spruce.
They are symmetrically circular shaped, the tips are machine fitted.
The straight corner cross rib (cut off bar) is made from solid beech wood. It is CNC machined to the form of sounboard crown.

Traditionally circular shaped ribs support the symmetric crown of the sound board and conduce to the typical PETROF sound.


The bridges are a Petrof original design.
The treble bridge is made from a solid beech body with a genuine ebony cap in high treble section.
The bass bridge has a solid beech body with a foot bridge.
Both the bridges are blackened, machine notched and hand drilled for the pins.

The ebony bridge cap is used to most efficiently transfer of high frequencies to the soundboard. The bridges design contributes to the wonderful European sound of the PETROF pianos.


The Breeze has agraffs in the bass and middle section, capo V bar in treble and front and rear pre-tuned duplexes in high treble.
PETROF utilizes laser positioning of its duplex bridges (frets).

Hammer heads

The PETROF utilizes hornbeam hammer shanks and Abel or Renner hammers made in Germany with hornbeam or walnut moldings.

Abel and Renner hammers are one of the worlds best, made from very special hammer felt. These hammers enable PETROF to obtain a wide scale of tonal color and power.


The Breeze is equipped with Petrof dampers. There is used the world top damper felt Laoureux France.

Used French felt is a guarantee of the highest dampers quality.
