Definitions

  • Woodwind instruments such as a saxophone, a flute, a clarinet and the like utilize a reed mouthpiece for producing sound with pitch variations as a function of breath-release pressure within the mouthpiece, a hollow tube resonating the produced tones and a plurality of depressable keys actuating valves which modify the effective tube length to produce frequency variations whereby in turn to produce musical notes as a function of the keys depressed by the player.
  • the distance between the mouthpiece and valve is generally several times the wave length of each musical scale.
  • the characteristic of each musical note is determined by the size, shape and the material of which the tube is made. Since the tube design is substantially uniform for woodwind instruments, the fingering is substantially the same for each woodwind instrument.

  • I provide an electrically operated musical instrument which includes groups of change-over switches ofa number corresponding to the number of keys which the conventional woodwind instrument has.
  • My instrument also includes groups of sound generators for generating notes of predeter mined frequencies in a given scale, current paths being provided to the generators by selecting combinations of change-over switches governed by combinations of key depressions on the musical instrument to provide notes of predetermined frequency generated by the sound generators.
  • the change-over switches have contacts a first group of which are provided on an external contact panel and the second group of which are provided on an internal contact panel, there being interposed between such external and internal panels an intermediate panel carrying movable contacts of the change-over switches.
