interesting, yet often strange, even the most peaceful movements requiring closest attention. If one of all these great works must be distinguished as the greatest, we would name the pianoforte quintet in F minor, Op. 34. Yet the very latest work, the clarinet quintet, shows the same freshness and originality of invention, wonderful thematic net-work, variety of distinctly expressed moods, and the finale displaying an unsurpassed skill in variations. The two orchestra serenades are real gems of spirited, delightful, well constructed music, one being for complete orchestra, the other for violas, ’celli, basses, reed instruments and horns. Besides the lively first and last movements and adagios they contain each a scherzo and one of them two minuets. The theme for the nine orchestra variations Op. 56 is taken from one of Haydn’s divertimenti for wind instruments. They crown Brahms’ glorious achievements in the writing of variations; for, far from being “mere algebraic experiments,” they are delightful and ingenious tone pictures of distinct character and mood, with a nearer or more remote relation to the principal theme. The composer has thus initiated a new field of independent orchestral music, already successfully followed by others. The instrumentation is prominently interesting. It is generally admitted that Brahms is very conservative compared with Wagner and Berlioz in the matter of instrumentation. At least he never allows orchestral colors to divert our attention from the higher, inner meaning of a work. Yet in this score and in all his other works for or with orchestra, there are many features either of wonderful brilliancy or peculiar colors, which as novelties are worth studying. The finale, built upon a much repeated bass figure, successively joined by the different groups of the orchestra with other themes, reaches a beautiful climax in the pompous return of the original melody.
