Final answer:
Schoenberg's Der Mondfleck integrates a chamber orchestra and a Sprechstimme, a singer who half speaks, half sings the text, yielding a characteristic atonal, pitch-centred music.
Step-by-step explanation:
The performing forces in Schoenberg's Der Mondfleck are characterized by a unique set up of a small chamber orchestra and a singer, or Sprechstimme, who half speaks, half sings the text. The chamber orchestra includes a variety of instruments: strings, woodwinds, brass, percussion, celesta and harmonium. The use of Sprechstimme, an unusual method of vocal production halfway between singing and speaking, combined with the diverse instrumental ensemble, creates a characteristic atonal, or pitch-centred, music style representative of Schoenberg's Second Viennese School.
