Symphony Hall in Boston opens its doors tomorrow afternoon to the start of another concert season by the Boston Symphony Orchestra. The program, which is to be repeated the following night, consists of two well known works: the "Eroica" or Third Symphony of Beethoven, and the Second Symphony of the Finnish composer Jan Sibelius.

The former is one of the most famous of all orchestral compositions and has become one of the standard concert pieces for such an occasion as the opening of a musical year. Originally dedicated to Napoleon the Consul, it lost that inscription when the composer thought that the ambitious Corsican had presumed too much when he titled himself Napoleon the Emperor. Its "heroic" qualities have survived both in the magnificent music and in the fitting name "Eroica," and the performances under Koussevitzky should more than do justice to the great score.

Sibelius Symphony

The works of Sibelius have become an especial province of Dr. Koussevitzky in recent years, and the Finnish composer's Second Symphony seems to be a particular favorite. The combination of Sibelius and Koussevitzky is almost unbeatable anyway for the latter manages to realize the superbly tense restlessness which the former has created. The Second Symphony is in danger of being over-played at the present, but few can fail to enjoy the work.

Sanders Theatre is to house the Federal Music Project's State Symphony Orchestra next Sunday evening in a program headed by Tschaikowsky's First Symphony and including Tartini's Concerto in A Major. These concerts are not of the first or even second rank technically, but they are almost invariably quite worthwhile as a musical experience, and the low price of admission is an added attraction.

For those who like a virtuoso series, the office of Aaron Richmond is offering five concerts throughout the winter featuring Flagstad, the Philadelphia Orchestra, Shan-Kar, Marian Anderson, and the Don Cossateks. The group is certainly remarkable, and inquiries may be directed to Mr. Richmond at 12 Huntington Avenue in Boston.
