Since 2011, Klangvereingiung’s folk music ensemble, called Klangvierterl, has performed primarily in Vienna and surrounding cities. The quartet’s guiding principle is to interpret classic Viennese Music in a contemporary setting. In addition to concert appearances and recording, the group has appeared in the television program Klingendes Österreich and performed at the Schrammelfestival and the Oster-Erlebnismarkt. 

„A brilliant quartet of a special kind“ (NÖ Nachrichten)

The name Klangvierterl  signifies the connection between Music and Geselligkeit, or conviviality, as well as the relationship between the four musicians, with reference to the fact that a vierterl, or quarter, forms a part of the Klangvereinigung. The word vierterl can also refer to a quarter note in sheet music, and it is not a coincidence that this is a play on words for the way in which one orders a vierterl, or quarter of a liter of wine at a Heuriger (wine-tavern).

Bernhard Winkler (Violin), Leopold Winkler (Clarinet), Gerald Mair (Contrabass, Voice, Arrangements) and Dragoljub Brkic (Accordion) are all experienced chamber musicians . At the beginning of their collaboration, they specialized in Viennese music, but have since expanded their repertoire to include a variety of genres.

The repertoire of the ensemble includes Wienerlieder [Viennese Songs], Polkas, Waltzes, Tangos, classical chamber music, as well as contemporary pieces. If something is not yet in the repertoire, the Klangvierterl is ready, willing, and able to perform custom arrangements of your personal favorites.

„The four musicians […] are masters of their instruments and as a quartet, even in this unique constellation, are excellent“ (NÖ Nachrichten)
