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 Leoš Čepický, 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.

In the 2019 season, the first four quartets of the composer Jaroslav Krček filmed the CD, in 2021 another four quartets and are currently preparing for the premiere of the third series of his quartets, as well as their immortalization on the CD. (Unfortunately, in the 2020 season, the Quartet was abolished due to the worldwide pandemic of many interesting projects, including a tour of Japan and Italy, but for example, performing at the Dvořák Prague festival, Jakub Jan Ryba festival, or Forfest in Kroměříž.


In the current season, the Quartet traveled to festivals to Levoča in Slovakia and Bourlingster in Luxembourg.
