Petrof Grand Piano P 237 Monsoon

PETROF P 237 Monsoon acoustic grand piano

PETROF P 237 Monsoon As a 237 cm professional grand piano, it creates an optimal balance between size and concert power. Its delicate, balanced, and romantic tone, fast mechanical response, and wide dynamics make it versatile for large halls and studios.

PETROF's European grand piano tradition

PETROF continues the Czech piano manufacturing tradition founded by Antonín Petrof in 1864. In the Master Series line, the high share of manual labor, selected European materials, and individual voicing tailored to the model shape the recognizable soft, rounded, and romantic tonal character of PETROF.

Resonance spruce soundboard

The soundboard, made of resonance spruce with an active area of 1.616 m², is thinned according to the model's string scale. 14 ribs support the flexibility of the soundboard and the even distribution of string energy. The result is a warm fundamental tone in the bass, a singing timbre in the middle register, and a clear, yet non-harsh projection in the treble.

Construction and tonal stability

The cast iron frame, manufactured using the wet sand casting method, bears high string tension. The multi-layer beech pinblock, inner rim built from beech and maple layers, solid maple bridges, and German-made Röslau steel strings work together for resonance transmission, tuning stability, and long-term durability. Brass agraffes for keys 1–53 and front-rear duplex scales precisely control the speaking length and harmonic structure of the string.

Action, keyboard, and pedals

The professional PETROF configuration action transfers the pianist's touch to the hammer in a fast and controlled manner. German-made hammer heads are individually voiced for each instrument. Tangentially cut spruce keys are individually balanced with lead, and ebony wood is used for the black keys. Unacorda, sostenuto, and sustain pedals provide full expressive possibilities for the classical grand piano repertoire; the hydraulic soft-close fallboard ensures safety for daily use.
