Piccolo heckelphone

The piccolo heckelphone is a very rare woodwind instrument invented in 1904 by the firm of Wilhelm Heckel in Wiesbaden-Biebrich, Germany. A variant of the heckelphone, the piccolo heckelphone was intended to add power to the very highest woodwind register of the late Romantic orchestra, providing a full and rich oboe-like sound well into the sopranino range. A transposing instrument pitched in F, a perfect fourth above the oboe, its range as described in contemporary fingering charts is from B to G♯, though it can reach tones as much as a third above this.

Following the basic principle of the heckelphone, the piccolo heckelphone in F has an extremely wide bore with large tone holes. The angle of the instrument's conicity is quite wide (though not as wide as that of a saxophone), giving it a characteristically strong and powerful tone. The instrument is built in one section with a detachable bell, and has simple-system German fingering.

Richard Strauss, who scored for the heckelphone on a number of occasions, was an early enthusiast of the piccolo heckelphone, even using it in a performance of Bach's second Brandenburg Concerto, where it played the high trumpet part in the last movement. In 1915, Strauss requested that a piccolo heckelphone in E♭ be built for use in his composition Eine Alpensinfonie. Named the terz-heckelphon, Strauss ultimately did not score for it, though a handful were built.
