These particulars have great interest in musical enquiry, and help us to see how fortuitous has been the growth of the scale, and how characteristically “_minor_” the music of different races seems to us, whilst in reality quite outside our scale and distinct from it in development. The flat fourths I have found to be persistent in Chinese music, and for very good natural reasons, as will be fully shown in subsequent chapters on the Chinese ancient instruments. The very low sounds given by these flutes are necessarily weak and have no penetrative power, nothing like what we should expect to be adequate for ceremonial use, or for the purposes to which we imagine the flutes applied in public life. A procession, for instance would, by the mere noise arising from walking drown the sounds, unless the walkers trod in sand. The conclusion I am driven to is that the skill of the players was devoted to eliciting the shrill harmonic tones, and that the low range of tone was seldom brought into requisition. The length of the pipes suggests this view, and the extreme slenderness seems to be adopted for the purpose; since it is inimical to volume of tone, yet favours under strong breath pressure the eliciting of high tones. Any day some new discovery may confute our speculations; but still we cannot but indulge in them. We, with modern eyes, look upon these flutes only as musical instruments; but to the Egyptians every tone heard alone or in combination, every movement, every gesture of the player had its mystic meaning, and its occult significance in association with rituals and observances and ceremonies. In these early ages, double flutes appear to have flourished everywhere amongst neighbouring nations; and the single flute, if the pictured representations and designs are to guide us, was comparatively rare. We note the fact, but, as to why the double flute was popular, we are quite in the dark. Egyptians, Assyrians, Babylonians,—which nation first had them? Far back as our spoils from the ancient cities and tombs and palaces and temples may date, it is very certain that the double flutes had their origin in far earlier times, and had passed through periods of evolution from some type ruder than the instruments which we find depicted. I have remarked how the added tone furnished by Lady Maket’s flutes indicates a large advance in the progress of civilization in her day, for probably flutes without such had had their run of popularity, perhaps centuries earlier. So that, when we speak of primitive pipes and primitive tetrachords, we think of long anterior dates, long before the particular instruments were fabricated which we have cognizance of. Advance is very slow.
