CHAPTER X.
FlUte-pipes and Eeeds. It will be found on examination, that in all wind instruments, the air contained in the tubes of such instruments is set in vibration, either by blowing against a sharp edge, at or near the mouth of the tube, as in the flute and the flue pipes of the organ ; or by the vibration of some solid body placed in a similar position, as in the clarinet and the reed pipes of the organ. We shall proceed first, to investigate the conditions which determine pitch, quality, and intensity in the former class of instruments.
