As there are five finger holes and one thumb hole to each, it is clear, on consideration, that these cannot have been di-aulos, but that they were used as single pipes requiring two hands to play either; for the six holes would be unmanageable, and the holding altogether insecure under one hand. In my view, these are distinctly specimens of the mon-aulos, “the sweet mon-aulos,” praised by the poets; and there can be little question that the reeds used were soft and fine, and that the Greeks had acquired a skill in making them. Probably, they differed as much from the common _arghool_ as the reeds used by Lazarus in his clarionet differed from those of the street player on the yellow clarionet of past days. I have given the names of the notes against the holes. The thumb holes out of line will be understood as showing what otherwise is out of sight; but it makes the series of holes clearer. In the one pipe it is the G hole, in the other it is the A. You will notice that there is a curious interval of a minor third, which doubtless had some special importance in Greek measures. The pitch is, as we say, double pitch in respect of length of pipe, so that the low B♭ is truly the four foot note; but we speak, in general terms, of the scale given by the pipes as a two foot scale. It is a pity that, as at present disposed in the case, the pipes are unsuitably placed, being head to tail,—as annoying to look at in an instrumental regard, as to an archæologist it would be to see a statue exhibited standing on its head. But perhaps I may get this anomalous relation altered, for the observer misses the proper relation of the flutes to each other. The nature of the beating reed greatly affects the scale. That which I have recorded is given by the particular reed I have used; another reed might make one or two tones difference. Again, there is the question whether these pipes had one, or two, or three bulbs, although only one was found. I am inclined to believe that the originals had but one bulb, because the two pipes evidently indicate that one flute was used for one mode, and the other flute for the other mode, with only the difference of a tone between them.
