Heckelphone-clarinet

The heckelphone-clarinet (or Heckelphon-Klarinette) is a rare woodwind instrument, invented in 1907 by Wilhelm Heckel in Wiesbaden-Biebrich, Germany.

Despite its name, it is essentially a wooden saxophone with wide conical bore, built of red-stained maple wood, overblowing the octave, and with clarinet-like fingerings.

It has a single-reed mouthpiece attached to a short metal neck, similar to an alto clarinet.

[2] The instrument is not to be confused with the heckel-clarina, also a very rare conical bore single reed woodwind by Heckel but higher in pitch and made of metal, nor with the heckelphone, a double reed instrument lower in pitch.

In his 1931 catalogue, Heckel asserts that "the clarinet-like tone of the instrument is excellent, extraordinarily harmonious, and powerful; nor is it sharp or metallic like that of the alto saxophone".
