How far this is accurate can only be determined by an examination of what was being done by others about the same time; but it may be safely said that, in the absolute sense, no enduring art form has been the creation of one man. There has always been a growth, although it is no doubt true that at a certain stage of the process some one with genius has, as it were, put the top stone on the edifice. Robert Schumann, writing on this topic, uses the following characteristic words:—“The world is large. Be modest! You have not yet discovered and contrived what others before you have not already imagined and found out;” the meaning of which doubtless is that of absolute originality there is very little at any time, and what stands in its place (and this will seem more or less according to our knowledge or ignorance of what has already been done) is really the fruition of many past influences, plus the genius of the man who assimilates and gives them fresh shape. [Sidenote: =J.S. Bach=] John Sebastian Bach (1685-1750) was probably the most original genius the art of music has known, but it would be idle to deny that he was deeply indebted to his predecessors, Frescobaldi, Buxtehude, Klemme, and Pachelbel. Take, for example, the history of what now goes under the name of Programme Music. What Liszt aimed at in his Symphonic Poems, and what Richard Strauss’s remarkable creations—“Don Juan,” “Till Eulenspiegel,” “Ein Heldenleben,” and the rest, attempt to express, was already in the minds of composers a very long while ago. Mr. Corder, in his article on this subject in Grove’s _Dictionary_, states that W. Byrd (1560) wrote a battle-piece for Virginals, and John Mundy, another English composer of that period, published a so-called “Fantasia on the Weather,” professing to depict fair weather, lightning, thunder, etc. Krieger (1667) gives us a four-part vocal fugue entirely made up of an imitation of the mewing of cats! There is also the fairly well-known Cat’s Fugue by Domenico Scarlatti, suggested of course by his cat accidentally walking over the keys of his harpsichord. Bach, Handel, Haydn, and Beethoven are also among the great ones whose works occasionally tended in a like direction. It is the same with any other distinctive feature in music, and therefore, while undoubtedly Haydn did very much for its expansion, the truth is that the form of the String Quartett was a gradual development, and not the creation of any single mind. As to the vitality of the music of different composers, which is another matter, Boccherini, a contemporary of Haydn, wrote more quartetts than that master, and they were highly esteemed during his life-time; but, save the musical student, who knows or plays them to-day?
