Workshops & Teaching

Petra gives workshops in jazz improvisation for string players. Improvisation is often the part in Classical music education that is missing, but ability to improvise as little as a little tune/melody improves a musician’s understanding of music. A welcome addition to the perfomer’s skills, it helps with freedom of expression, with getting rid of stress and stage fright, improves playing techniques, sound and most of all it motivates to play and practice.
Petra, through her jazz education as a performer and arranger and studies of Ethno and traditional styles uses simple tricks to free up a musician’s expression and performing skills, and is useful to musicians of any level.
She offers workshops for different schools, students, established musicians and teachers. She is available as well to give one-on-one private lessons.
