About us

The Czech Philharmonic Quartet (CPQ) was established by the initiative of members of the Czech Philharmonic Orchestra in 2000. The quartet performers are Olga Šroubková, 1st violin, Viktor Mazáček, 2nd violin, Jiří Poslední, viola, and Jakub Dvořák, cello. The immense talents of these musicians and long-term experience in chamber music are great preconditions for their top-class performance. The tone of the CPQ is highly valued by professional international critics.

The CPQ regularly participate in the chamber cycles of the Czech Philharmonic Orchestra, in various festivals and in events organised by the Circle of Friends of Music, both over the Czech Republic and abroad (Great Britain, Luxembourg, Germany, Japan, Israel, China and Slovakia).

The CPQ also participated in a Japanese project titled “Therapy by Mozart”: within the project, the CPQ recorded a series of Mozart’s chamber compositions. For the famous Japanese Octavia Records Label, the CPQ recorded the “Haydn” Quartets and the “Prussian” Quartets by Mozart.

In autumn 2017, the CPQ recorded a CD with compositions by Leoš Janáček “On an Overgrown Path” and “In the Mists”, published by Arco Diva.
