RUSSIAN CHURCH MUSIC.

The concert in Sanders Theatre tonight given by the Russian Cathedral Choir of the Church of Saint Nicholas, New York, offers an opportunity to hear a really unique performance. In the first place, the range of the Russian male voice is far beyond that of the occidental basso, in some cases going a whole octave lower. The singing is always unaccompanied, which necessitates absolute control of time and pitch. Then, although all of the old Slavonic Church music has been preserved, in the last century there has been a great revival in its composition, and musicians like Tschaikowsky and Rachmaninoff have contributed to its stock. The concert will be very much worth hearing, if only for the unusual nature of the performance.
