so direct and complete, is taken as matter for contrapuntal treatment. The adagio is also a masterpiece, approached, perhaps equalled, but not surpassed by Beethoven. Polyphony is the life of these quintets; but it is not purely scholastic polyphony. Mozart once said to Michael Kelly, "Melody is the essence of music. I compare a good melodist to a fine racer, and counterpointists to hack post horses." But in these quintets the counterpoint is so melodious that the tricks and strainings of the pedagogue are never brought to mind. Here may also be mentioned the quintet in A major for clarinet and strings (1789), written for Anton Stadler, a dissipated fellow, a toss-pot, and riggish. But Mozart loved him because he blew cunningly the clarinet, and he went about with him, and ate with him, and drank with him. Although it is freer in form than the great quartets, and the quintets in G minor, this clarinet quintet stands beside them in its grace tinged with melancholy, its contrapuntal skill masterly disguised, its divine melody.

This important original has served as a model for many posthumous portraits of Mozart.] A review of the symphonies of Mozart is a summing up of the history of the symphony in the eighteenth century from childhood to maturity. He was eight years old when he wrote in London his first symphony. It is in sonata form: allegro, andante, finale: he uses the orchestra of the predecessors of Haydn, viz., two violins, viola, bass, two oboes, and two horns. These early symphonies of Mozart are relics of the time when German instrumental music was still in a comparatively crude condition, and they are chiefly interesting from the historical point of view; for even Köchel, the devoted admirer of Mozart, says that they are wanting in character and that the motives are without development. Look for instance at the first symphony. The allegro has one hundred and eighteen measures; the andante fifty; the presto ninety-one. According to the fashion of the old suite the three movements are in the same tonality. The symphonies of 1764 and 1765 are in the same form; in two of them the andante is in a different key from the other movements. It was in 1767 that Mozart first introduced the minuet, which was, however, without a trio. The seventeen symphonies written from 1767 to 1772 show an advance in instrumentation rather than in growth of form. The early ones were composed for the eight-part orchestra, the foundation of modern orchestral works. In the second, the two horns are replaced by two clarinets, and a bassoon is added. Now the use of the clarinet was then rare. Christopher Denner made the first clarinet in 1701. Gossec wrote for the instrument in 1756, and it was first heard in England in Christian Bach's opera "Orione" (1763). Mozart used it also in a symphony written in Paris in 1778, and he did not introduce it again until 1783.
