The wide connotation which must be accorded to the word “dancing” is illustrated by what the Bedouin Arabs understand by it. They are a race which, as is well known, has retained many beliefs, customs, and practices which have been handed down from time immemorial; therefore the evidence afforded by them is valuable. By dance, which they call _raḳṣ_, they understand every rhythmic movement of hands or feet, whether remaining on the same spot or not[10]. Of them as of all other peoples rhythm is as inseparable from the movements of the dance “as it is from other bodily functions, and therefore belongs to it without saying[11]”; but, as the Arabs show, rhythmic movements can be performed while standing on one spot; emotions can be expressed by the rhythmic movements of the arms and of the body and of the head while the legs may be more or less motionless. “The human instinct of play,” says Crawley, “is closely connected with the human love of excitement. The dance satisfies both, and its rhythmical character also makes it suitable for the expression of the most solemn and controlled emotions. It is at once the servant of Apollo and of Dionysus[12].” The close, one may almost say the inseparable, connexion between the dance and music is as marked in its sacred as in its secular character. In the first instance it is the rhythmic instinct which demands this, so that among many savages the “music” which accompanies the dance is the mere clapping of hands, or the striking together of pieces of wood, or the beating of the tom-tom, all in rhythmical time. The same is also found among some peoples more advanced on the path of culture, though they usually add the sound of other instruments, among which the flute figures prominently. Singing is, of course, and always has been, another favourite accompaniment to the dance. The Bedouin Arabs accompany their dances by the beating of cymbals or of hand-drums, or by clapping of hands; sometimes singing accompanies the dancing[13]. This was also the case among the Israelites. III
