"Arina is one of the best language coaches that I have worked with at the BBC National Chorus of Wales in the past twenty five years, and the best Russian language coach we have engaged. Her work for the 2019 BBC Promenade Concerts was especially appreciated.

In rehearsals, she speaks her native language very clearly and with great care, and enjoys helping non-Russian speakers to understand how to produce all the rich sounds and colours of that wonderful language.

Arina is herself an excellent singer, and is well equipped to help singers of all standards to perform at their best when singing in Russian. She has a relaxed and friendly manner, but insists on the highest standards.

I warmly recommend her to all those who are interested in Russian Lyric Diction."

Adrian Partington, director of the BBC National Chorus of Wales
