The Lupophon[1] is a woodwind instrument invented and manufactured by Guntram Wolf of Kronach, Germany. It is in effect a modified heckelphone, with a slightly smaller bore and range down to low F. The lower portion of the instrument is folded back on itself in order to manage the considerable length of the tube, somewhat in the manner of a bass clarinet. The addition of the 4 lowest semitones allows it to cover the full intended range of the heckelphone part of Richard Strauss' Eine Alpensinfonie, which descends beyond that instrument's lowest note.
The first chamber composition featuring the instrument in a solo capacity, PLP for lupophone and two pianos by Samuel Andreyev, was premiered by Martin Bliggenstorfer in Amsterdam on 15 March 2011.
