The symphonium was the object of Charles W. Wheatstone's (1802-1875) British patent No. 5803, "A Certain Improvement or Certain Improvements in the Construction of Wind Musical Instruments,"awarded June 19, 1829. According to the patent text, "These improvements are applicable to instruments in which the sounds are produced by directing a current of air against metallic springs or tongues fitted over and vibrating freely within or over corresponding apertures formed in plates. Several of these springs being placed in apertures arranged parallel to each other, sideby [sic] side in a plate, and tuned to the notes of a common chord, consitute one of the simplest forms of a wind musical instrument, known in Germany under the name of the Mundharmonica, and in England by that of the Æolina. Finger keys have also been added to such instruments, somewhat similar to those of flutes, but always placed at such distances apart as to allow space for the fingers to apply themselves to each key, when the instruments are held in such positions as for the hands to apply themselves thereto in the manner of fingering the flute or flageolet. In these improved keyed wind instruments, the springs are brought so close together that they occupy little more space than in the Æolina before mentioned. In fact, eight springs may be placed in the space of an inch-and-a-half, and their corresponding keys may also be brought much closer together than hitherto, and the wind chest made much smaller than has yet been done for a similar number of notes. Several forms of this instrument in one of which the wind chest is superseded by portable bellows, are given." | Charles W. Wheatstone |
