His symphony, which is in D major, is so ebullient with life that its dashing first subject cannot brook more than a few measures of slow introduction. The second subject is simpler, but no less joyous. The thematic work is scholarly and enthusiastic at the same time. The different movements of the symphony are, however, not thematically related, save that the coda of the last movement is a reminiscence of the auxiliary theme of the first movement. The andante, in which the 'cellos are very lyrical, is a tender and musing mood. The presto is flashing with life and has a trio of rollicking, even whooping, jubilation. The finale begins gloomily and martially, and it is succeeded by a period of beauty and grace. This movement, in fact, is a remarkable combination of the exquisitest beauty and most unrestrained prowess. Another orchestral work of great importance in American music is the "Sylvan Suite" (op. 19), which is also arranged for the piano. In this work the composer has shown a fine discretion and conservation in the use of the instruments, making liberal employment of small choirs for long periods. The work is programmatic in psychology only. It begins with a "Midsummer Idyl," which embodies the drowsy petulance of hot noon. The second number is "Will o' the Wisps." In this a three-voiced fugue for the strings, wood, and one horn has been used with legitimate effect and most teasing, fleeting whimsicality. The third movement is a slow waltz, called "The Dance of the Sylphs," a very catchy air, swaying delicately in the bassoons and 'cello; a short "Evening Song" is followed by "Midnight." This is a parade that reminds one strongly of Gottschalk's "Marche de Nuit." The march movement is followed by an interlude depicting the mystery of night, as Virgil says, "_tremulo sub lumine_." The composer has endeavored to indicate the chill gray of dawn by the ending of this movement: a chord taken by two flutes and the strings shivering _sul ponticello_. The last movement is "At Daybreak." Out of the gloom of the bassoons grows a broad and general luminous song followed by an interlude of the busy hum of life; this is succeeded by the return of the sunrise theme with a tremendously vivacious accompaniment. Other works of Brockway's are: a cantata, a set of variations, a ballade, a nocturne, a Characterstueck, a Fantasiestueck, a set of four piano pieces (op. 21), and two piano pieces (op. 25). All of these, except the cantata, have been published. Two part songs and two songs with piano accompaniment have also been published; a violin sonata, a Moment Musicale, and a romanza for violin and orchestra have been published in Berlin. These works all show a decided tendency to write brilliant and difficult music, but the difficulties are legitimate to the effect and the occasion. The Ballade works up a very powerful climax; the Scherzino swishes fascinatingly; and the Romanza for piano is a notably mature and serious work.
