Mr. Converse has made two heroic ventures onto the still unwon but yielding field of American grand opera. 'The Pipe of Desire,' with text by George E. Barton, a one-act opera, is in mood a reflection from the poets of the Celtic twilight. It was given a special production of three performances in Boston, in 1906, and experienced a brief revival, in March, 1910, at the Metropolitan Opera House in New York, and in the following January in Boston. A second opera, in three acts, 'The Sacrifice,' dealing with a romantic Spanish-Californian subject, is regarded as showing a marked advance in operatic style. It was produced by the Boston Opera Company in March, 1911, with a measure of success, but the scope of its bearings has not yet been extended. Mr. Converse's most recent large work was the composition of the music for the 'Pageant and Masque of St. Louis,' May 28-31, 1914, a broad and vigorous piece of writing. In general, his music is of strong fibre, harmoniously and melodically and warm in color, though his style has not yet broken wholly away from its academic moorings. For several years after 1902 he served as instructor and professor in the musical department of Harvard University. IV A very substantial and influential personality in American musical life is that of Ernest R. Kroeger, who was born in St. Louis, Mo., August 10, 1862, and whose activities have ever since been identified with that city. The list of his published compositions is enormous and comprises works in many forms. As is the case with most American composers, his orchestral and chamber music works remain in manuscript, and consist of three 'symphonic overtures,' 'Sardanapalus,' 'Hiawatha,' and 'Atala,' the first Oriental in character, the two latter Indian, overtures on the subjects of 'Thanatopsis' and 'Endymion,' a 'Lalla Rookh' suite, two string quartets, and, for piano with strings, a trio, quartet, and quintet.
