The flute itself could not be called slender, being interiorly three eighths of an inch; and, moreover, it was but the casing that was of brass, and that only with flutes after the invention of that sectional arrangement of sliding cylindrical pieces over each aperture, the tube itself being of ivory, or of elder, or of sycamore. Thus, then, the question arises. What slender brass had Pindar in mind?
Accepting the prose as the more literal translation, note the “and,” as if Pindar meant, and then through the reeds, and further it may be of importance that the plural is given “reeds.”
Although I have presented the picture of the two flutes that in style accord with the flute designed by the sculptor as if that upon such Midas played, I believe that a scrutiny of dates forbids the supposition; those flutes will prove to be of too late a date, Midas is certainly more likely to have used the double flutes pictured upon the vases,—the bulbed flutes, and not the single ones fingered by the two hands. In the plural case, the two flutes would be rightly described, being the style with the two reed-pipes, one for each hand.
Accepting Pindar’s words literally—“slender brass”—I think that we must believe that he meant to describe the reed as of brass: a reed of slender metal through which the breath passed on its way, urging the reed into vibration. Now, what I would suggest is that, if silk reached Greece from China in those days, why should not the free reed? Actually it is of slender brass.
I have made experiments with the free reed upon my copies of the Greek flutes in the British Museum, and see very clearly the possibility of the adaptation of the free reed to the hollow cocoon-like bulb pictured of the flutes in the paintings upon the Etruscan vases, and which, as you have read, I interpret as being designed to hold a reed within it; the first, second, or third bulb being selected for the purpose, according to “the mode” of the particular piece of music that was to be played. The bulbs are quite large enough for holding the free reed of the requisite size and flexibility.
In the Chinese organ “Sheng” the little brass free reed is fixed on a small quill-like reed stem and is passed through a hole into the bowl that holds the series of reeds. The position of the reed for sounding is exactly the same as that which I am supposing for it in the bulb.
Again, it has been supposed from a remark made by an ancient reporter that a certain flute player in a contest was unable to play because of an accident by which his flute reed had become bent; that therefore it may have been a metal reed such as the free reed.
The question has also an acoustic bearing; according to Weber’s law, the free reed is amenable to variations of pitch: by its nature it is able to accommodate itself, and may be taken down an octave in pitch under the influence of the tube with which it is associated; but upon that descent of pitch being reached, it starts back again to its own pitch. Joining such a reed to the flute, I find that its pitch is lowered as each hole is in succession closed, but that at the last hole it refuses to speak at all. This shows that a different reed should be selected that would be flexible enough to accommodate itself to altered conditions of tube; but to obtain the right reed will demand a course of arduous experiment upon new ground, the best teacher being experience. I said that the reed refuses to speak. Here comes a noticeable fact: by extreme high pressure I can induce it to speak, and that powerfully. Have we not in this fact some hint—or, may be, explanation—of that strange demand of the Greeks, as it seems to us, for a bandage, a phorbeion, like a halter over the head, to prevent the bursting of the cheeks of the player? This intensely produced note may be the kind of note they wanted,—that which they prized and acclaimed in Midas. The probability is that the whole series of notes was produced on this high pressure system, in open air, and intended to be heard by a vast concourse of people. When I played softly or with average strength of breath, I found that I could not take the reed beyond a fourth. Does not this appear to account for the limitation to four holes which so long prevailed? In our own course of evolution of instruments from early times progress has been slow; many centuries passed before the first little brass key was invented and applied to flutes. With the clarionet it was the same: the sudden burst into new life being due to one man,—Denner. From the first to the last period in the development of Greek flutes there were no doubt well marked transition stages of which we possess no record: new inventions equally momentous to them as to us, and upon which new players started into pre-eminence. Midas was credited with the invention of the particular flute upon which he won renown; and it may have been that Pindar intentionally specified it, and that it may have consisted in the application of a free reed of slender brass to obtain a greater range of notes.
The free reed in the way that I have suggested was equally applicable to the double and to the single flute; and therefore, whatever the kind of flute upon which glorious Midas played, and won his laurel wreaths and his immortal renown, the special epithet of Pindar would hold true:—
Through slender brass it flows.
