Julia Czerniawska grew up in a family of musicians and began playing the violin at the age of six. After completing her violin studies in Poland and Austria (at the University Mozarteum Salzburg), she performed with various European orchestras and smaller ensembles. From 2011 to 2017, she was a permanent member of the first violins at the National Theater Mannheim. During her classical training, she discovered her fascination for jazz and improvised music. Through her involvement in various bands and her jazz studies with Didier Lockwood in Paris, she developed her musical freedom and joy in exploring different musical styles. She lives in Berlin, where she leads her own projects and participates in recordings and concerts in both the classical and jazz fields. Her projects include the CBA String Trio and the Julia Czerniawska Group, with which she performed at the Weltivale in Flensburg in 2024.
