In considering the compositions of this man, who died before he was thirty-six, and spent much time in travel, the most superficial investigator must be struck by the mere number. There are 20 dramatic works; 2 oratorios, a funeral hymn, 3 cantatas, and the reinstrumentation of 4 oratorios by Handel; 66 vocal pieces with orchestral accompaniments; 23 canons and a collection of songs; 48 pieces for the church, and 20 masses, including the Requiem, which however was probably completed by Süssmayer; 22 pianoforte sonatas and fantasias; 17 organ sonatas, 16 variations for bugle and pianoforte, 23 little pieces, and 11 sonatas and pieces for four hands on two pianofortes; 45 sonatas for violin and pianoforte; 8 trios, 2 quartets and 1 quintette for pianoforte and strings; for strings alone there are 3 duos, 3 trios, 29 quartets, 8 quintets; then there are 2 quartets with flute, 1 with oboe, 1 quintet with horn; 10 concertos for violin, 1 for two violins, 1 for violin and viola, 28 for the pianoforte, 1 for two pianofortes, 1 for three pianofortes, 1 for bassoon, 1 for oboe, 4 for flute and 1 for flute and harp, 5 for horn, 1 for clarinet,--in all 55; in dance music there is one gavotte, 39 contradances, 56 waltzes, 96 minuets, a pantomime and a ballet; there are 27 different pieces of instrumental music, as marches, adagios, etc., 33 divertissements, serenades or cassations, all pieces of long breath, including each from 10 to 12 movements; there are 49 symphonies. These authentic works, accepted by Köchel, number in all 769 compositions. Then when one reflects on the quality of the music and its artistic value, when one finds in nearly each work the traces at least of genius, and reflects that a third of them are masterpieces, he begins to realize the might of the man. He was naturally the most spontaneous of musicians, and in this respect--in pure creation--without doubt the greatest of them all. Rarely are seen such fecundity and such versatility. Unlike Handel, when a work was finished, it was finished; it did not enter again into another composition. The charge of plagiarism was never brought against him except in one instance: the religious march in "Idomeneus" was traced by a friend to the march in Gluck's "Alceste." He wrote as though he could not help it. Jumping from the bed, he ran to the pianoforte. The barber found him restless. His mind was preoccupied at table. In travel, the landscape, the very motion of the carriage stimulated his imagination. He was constantly jotting down his thoughts on scraps of paper. Much of his greatest music was composed, even in detail, in his head before he took his pen. The conversation of his friends, noises in the house or street did not distract him. His faculty of concentration was incredibly developed, and Constanze said that he wrote his scores as though he were writing a letter. And so his inspiration, as shown in the hasty composition of the "Don Giovanni" overture, reminded Victor Wilder of
