The Lupophon is a woodwind instrument developed by Guntram Wolf of Kronach and Benedikt Eppelsheim of Munich, Germany, manufactured by Guntram Wolf. The instrument takes name after the Italian translation of the inventor's surname (lupo standing for wolf), as the sarrusophone, the saxhorn, the saxophone, the heckelphone, the rothphone had been called after their inventors. 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 saxophone. 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.
