the soulful clarinet solo in the allegretto of the Seventh, or the weird effect of the low notes of the horn in the _trio_ of the scherzo of the Seventh Symphony? Beethoven held the trombones in great reserve, but whenever he employed them the effect was impressive, as for instance in the _finale_ of the Fifth Symphony and the storm of the Pastoral Symphony. Two famous passages in his symphonies, passages that have provoked angry disputes, are made remarkable by a singular use of the horn in which the laws of tonality are set at nought. Beethoven was the first that knew the value of the kettle-drums. He first raised the drum to the dignity of a solo instrument, as in the Fourth, Fifth and Ninth Symphonies. His instrumental effects went hand in hand with the development of the melodic idea. The different tone-masses are used in conversation; or a solo instrument announces the return of the theme; or the whole orchestra rages violently and then stops suddenly to listen to a far off voice. It would be impossible in an article of this brevity to speak of his manifold effects of instrumentation, or of the characteristics of his compositions in detail. Among his instrumental works are the 9 symphonies, overture and music to "Egmont," overture and music to "Prometheus," "The Battle of Vittoria," 9 overtures, 5 concertos for pianoforte and orchestra, 1 triple concerto, the Choral Fantasia, the violin concerto, 16 quartets for strings, 8 trios for pianoforte and strings, 10 sonatas for pianoforte and violin, 2 octets for wind, 1 septet for strings and wind, 1 quintet for pianoforte and wind, 5 sonatas for pianoforte and 'cello, 38 sonatas for pianoforte, and 21 sets of variations for pianoforte. The chief vocal works are "Fidelio," the two masses, the oratorio, "Christus am Oelberge," "Meerstille und glückliche Fahrt," the aria "Ah perfido!" and 66 songs with pianoforte accompaniment.
