I have Doctorate degree in Viola Performance, and I teach violin and viola to kids, students (undergraduate and graduate level), and adults, who want to improve their playing. I have 10+ years of experience as an orchestra and chamber musician, so I can help with audition preparation as well, give comments on your playing, technical and musical suggestions (unless you play like Heifetz or Perlman, in that case I might ask for a lesson from you).
The lesson can be done over Skype, Viber, or any other similar communication service. You need to have a camera, good internet connection, and a microphone. And a violin... or viola.
I speak English and Russian.
