the maddening rapidity of the Haxenschlagen. Enjoyment of crushing or rending destructible objects is characteristic of every age. I will cite as an example Goethe’s famed boyish exploit. After throwing from a window and smashing all his own store of breakable ware, incited by the appreciative cheers of the neighbours, he descended to the kitchen and seizing first upon a platter found that it made such a delightful crash that he must needs try another. He continued the entertainment until he had demolished all the dishes within his reach. In such a case, of course, enjoyment of the sound is not the only source of pleasure. Joy in being a cause is conspicuous when the clatter is self-originated, and sometimes renders even unpleasant sounds attractive, like scratching with a slate pencil, for instance. Besides, there is the satisfaction of impulses to movement, and often, too, the destructive impulse like that for overcoming difficulties is closely related to the propensity for fighting. In all this we have not yet touched on the subject of acoustic playthings, and it is so large that I can only throw out a few suggestions as to the likeness between primitive musical instruments and the noise-producing toys of children. We have seen that even the ape has discovered the principle of instrumental music, and puts it to practice by pounding with his hand on a stick or some hollow object. A baby does the same thing, and will take great delight in beating persistently and with a certain regularity on a table with his hand, on the floor with a stick, or on his tray with a spoon. If we regard these sounds thus playfully produced by beating on some foreign object, together with some notion of time, as affording probably the first suggestion of a musical instrument, we are met by two possibilities: either the stick itself is considered as the source of the noise or else the object it strikes is so regarded. In the simple instruments of savages both possibilities are realized. The Australian bell is a thick, bottle-shaped club of hard wood which, on being struck, gives forth a peculiar long note, and the drum with which the women accompany the dancing of the men is only a tightly stretched opossum skin, which they have been wearing on their shoulders.[95] Stringed instruments were derived from the bow; Homer sang of the clear sound which Odysseus drew from the tightly strung bow, and Heraclitus uses a complex figure of speech involving the bow and the lyre. The South African “gora” is only a modified form of this trusty weapon of the Bushman. The modification consists in introducing on one side, between the end of the cord and the bow, a trimmed, leaf-shaped, and flattened quill, which is placed upon the lips of the performer and set in motion by his breath.
