Ophicleide - LoveToKnow 1911 (Site not responding. Last check: 2007-10-19) |
 | | The ophicleide is almost perfect theoretically, for it combines the natural harmonic scale of the brass wind instruments having cup-shaped mouthpieces, such as the trumpet, with a system of keys, twelve in number, one for each chromatic semitone of the scale; it is capable of absolutely accurate intonation. |
 | | The ophicleide has in addition to its natural scale eleven or twelve lateral holes covered by keys, each of which, when successively opened, raises the pitch of the harmonic series a semitone, with the exception of the first, an open key, which on being closed lowers the pitch a semitone. |
 | | The ophicleide or bass of the harmony was made in C and in Bb, the contra-bass in F and in E5.4 3 The announcement of Weidinger's invention of a Klappentrompete, or trumpet with keys, appears in the Allg. |
