For the stay at home, the vagabond whose activity is restricted to the north bank of the Charles, there are only two musical events of especial importance; the monthly performances of the Boston Symphony Orchestra at Sanders Theatre, and the concert of the Pierian Sodality. The latter takes place this evening at 8.15 in Brattle Hall.

Entirely aside from the program which this, the oldest musical organization in America will present, the concert interest in the fact that Miss Ethel Leginska will act as guest conductor. As a pianist, Miss Leginska is in the foremost ranks of musicians; as a conductor she instills into the orchestra under her baton something of that inexplicable power which makes for life in a piece of music without attendant loss in its character. Of the program, two numbers chosen from a large group of excellent compositions, seem to deserves especial mention the concrete of Grieg and the Marche Hongroise of Berlioz. Grieg's work, concrete for piano and orchestra of which only the first of the three movements will be played, contains passages of the greatest beauty, particularly in the duets between the piano and oboe and the contrasts between the strings and the piano. It is a work which has not been played in Boston for some ten years, but should prove as popular tonight as it was a decade ago.

The Marche Hongroise is what might be expected from one who was not a romanticist but romanticism itself. IT is a theme taken from an old Hungarian war song which Berlioz incorporated into the Domination of Faust making of it one of the most brilliant of orchestral pieces.
