Russian matryoshkas (nesting dolls) in the hands of experienced Japanese musicians! The theremin, invented in Russia in 1920, is the earliest electronic instrument controlled without physical contact by the player. A matryomin is a matryoshka-shaped theremin. In this theremin concert, Mr. Masami Takeuchi, the foremost theremin player in Japan, will be joined by a matryomin ensemble. Theremins are very popular in Japan, so in July, 272 players made a GUINNESS World Record attempt by organising a huge matryomin ensemble, and were awarded the first-ever record for “The largest theremin ensemble”. After the concert, stay for a matryomin workshop, where you and your children will have the opportunity to learn some of the basic techniques for playing the matryomin.
