Theremin Lessons/Class in London

You should contact Lydia Kavina (www.lydiakavina.com). She gives regular Theremin workshops at the Faculty of Music at Oxford University!

Also have often a look here in the forums. Normally she announces her public teachings and masterclasses in Oxford under the nickname "tvox".

There are other occasions to meet one or more professional theremin teachers and other thereminists during workshops and festivals in Europe (continental... ;-) ):
