Astona - a video portrait (2019)

12 minutes

I took up the cello because I heard another boy playing it and fell in love with the sound. My teacher was Nancy Chumachenco. She expected a lot right from day one, and if you were a talented student she would go full steam ahead, not for just 30 or 60 minutes a week but a whole lot more. There was chamber music, too, and every year she would organise a summer school with students from other countries. Meeting kids from places like South Africa, Finland and the US as a twelve-year-old was so exciting, and it gave us a network of friends and colleagues to draw on as we got older. Not many people are lucky enough to be guided by someone like Nancy Chumacenco from the first time they pick up their instrument.

At the age of 15 to 17, I had the good fortune to attend Astona  International. I can attest to the fact that these years were the most formative in my musical education.

Astona International on the Swiss National News, July 21, 2018

I'd heard only positive things about Astona before I came and now that I’ve been there myself, I can with 100% certainty say that they’re true. I’ve learnt a lot, some of the things that I expected to learn and some skills that I did not realise I would. Astona is certainly an experience that I’ll never forget.  I greatly appreciate all your hard work and that of your fellow teachers. Thank you for an amazing opportunity!

After the intermission, Felix Mendelssohn-Bartholdy's octet for strings, followed by frenetic, well-deserved applaus and standing ovations.  Seldom does one encounter so much energy and enthusiasm as was audible and evident in all aspects of Astona."
