PETROF P 125 G1 Acoustic piano

PETROF P 125 G1 upright piano

PETROF P 125 G1 is a Higher Series model that complements a 125 cm acoustic platform with classic decorative elements. Its balanced sound volume and rich tonal range provide versatility for both ensemble and solo practice.

Higher Series and the PETROF sound character

PETROF's piano manufacturing tradition, continuing in the Czech Republic since 1864, focuses on creating a soft, rounded, and romantic tone through resonance spruce, a model-specific string scale, and individual voicing. In the Higher Series line, the PETROF P 125 G1 offers bass depth appropriate for its height, a singing middle register, and a clear treble.

Resonance spruce soundboard

The resonance spruce soundboard with an active area of 1.1852 m² is reinforced by 10 ribs. The soundboard profile is engineered to translate string vibrations into a wide dynamic range and balanced register transitions. The wet sand-cast iron frame, multi-layered pinblock, and maple bridges support tuning stability by keeping string tension consistent.

Action and keyboard

The PETROF upright action and individually voiced hammer heads serve to provide fast and precise touch transmission. The 88 keys create a natural sense of resistance from bass to treble. The left soft pedal softens the tone, the middle moderator pedal reduces volume for quiet practice, and the right sustain pedal lifts the dampers to release resonance.

Construction and daily use

Röslau steel strings, a sturdy wooden back frame, and a hydraulic soft-close fallboard create a reliable structure for long-term teaching and practice. The G1 cabinet adds decorative panels and elegant details to the classic profile; various wood finishes change the interior character of the model.
