The very depth and gravity of its pitch, made pervasive by its wealth of overtones, give to this primitive instrument a weird hold on the emotions. This combination of qualities we find well illustrated in the pahu and the ipu, the tones of which range in the lower registers of the human voice. The tone-character of the pu-niu, on the other hand, is more subdued, yet lively and cheerful, by reason in part of the very sharpness of its pitch, and thus affords an agreeable offset to the solemnity of the other two.
