As is clear, we have here simply observations, descriptions of that which the Semang has seen when watching the lemur in the forest. This description, of course, serves only as the material for the music of speech; that which is really musical is the refrain, which in this case consists simply of the word _kra_. This music of speech exalts and supplements the dance; when all parts of the body are in motion the articulatory organs also tend to participate. It is only the modern art-dance which has substituted an instrumental accompaniment for the voice and has thus been able to suppress the natural expression of emotions. But, even in our culture, the emotions receive active, vocal expression in the folk-dances of our villages. Musical instruments, in the strict sense of the word, are almost unknown to primitive man. Where somewhat complex forms occur, they appear to have been imported. Such, for example, is the bamboo nose-flute, occasionally found among the inland tribes of the Malay Peninsula. The nose-flute is similar to our flutes, except that it is blown from above instead of from the side, and is not played by means of the mouth, but is placed against one of the nostrils, so that the side of the nose serves as the tone-producing membrane. It has from three to five holes that may be covered with the fingers. This instrument is a genuine product of Melanesia, and was doubtless acquired from this region by the Malayan tribes. Of earlier origin, no doubt, are _stringed instruments_. These are to be found even among primitive peoples. The forms that occur in Malacca have, in this case also, obviously come from Oceania. But, on the other hand, an instrument has been found among the Bushmen and the neighbouring peoples which may be regarded as the most primitive of its kind and which throws important light on the origin of musical instruments of this sort. A bow, essentially similar to that which he employs in the chase, affords the Bushman a simple stringed instrument. The string of the bow now becomes the string of a musical instrument. Its tones, however, cannot be heard distinctly by any one except the player himself. He takes one end of the bow between his teeth and sets the string into vibration with his finger. The resonance of the bones of his head then causes a tone, whose pitch he may vary by holding the string at the middle or at some other point, and thus setting only a part of the string into vibration. Of this tone, however, practically no sound reaches the external world. On the other hand, the tone produces a very strong effect on the player himself, being powerfully transmitted through the teeth to the firm parts of the skull and reaching the auditory nerves through a direct bone-conduction. Thus, then, it is a remarkable fact that music, the most subjective of the arts, begins with the very stringed instruments which are the most effective in arousing subjective moods, and with a form in which
