The heckelphone, which resembles the oboe

The heckelphone performs at a range one octave lower than the oboe; it is a rare instrument that appears only in the works of Richard Strauss and Paul Hindemith . The pipe is red-painted maple wood, like a bassoon. Numerous new instruments were created in the late 19th and early 20th centuries, but they went out of vogue, rather than gaining acceptance. The heckelphone was one such instrument.
