The exceptional heritage of our ancestors

Meet the tallest upright of the PETROF brand, which boasts the greatest sound potential. Its size makes it ideal for discerning professional pianists and audiences. This is an instrument of masterly construction intended for music schools, (home?) interiors, and for the performance of musical works with orchestra. Its uniqueness is enhanced by the unusual design of the music stand, but lies most of all in its powerful, open and colourful tone.
