anyways, this is a tone poem that is performed like any other concert piece. The piece itself is pretty long and every act spans from 18 to 30 minutes each. It should be performed like an opera or a ballet, despite there being no acting or dancing involved.   instrumentation notes There are three oboes in total. All three double on bass oboe in the first movement. • The first clarinet part has two players: • One playing the upper line. • One playing the lower line,
