Grand piano P 284 Mistral

P 284 Mistral

Perfection without compromise

We present to you our masterpiece, the flagship of the PETROF brand - the Mistral concert grand. Measuring 2,840 mm in length it is our largest piano, and is beloved of musicians the world over chiefly for its tremendous bass and resonant treble. Artists find in it a trusty companion when performing the most demanding works; it also has a highly presentable appearance and possesses the soft, romantic tone so characteristic of all PETROF grand pianos.
