Heckelphone

The Heckelphone was only developed in the 20th century and with its dark, expressive character it rounds out the oboes’ tenor register. Because of its similar sound it can replace the baritone oboe. Richard Strauss was among the great composers who liked to employ the instrument which sounds an octave lower than the oboe, e.g., in his scores for “Salome”, “Elektra” and “Eine Alpensymphonie”
