Final answer:
The six contrapuntal devices used in a fugue are the subject, answer, countersubject, episode, stretto, and inversion.
Step-by-step explanation:
The six contrapuntal devices used in a fugue are:
- Subject: A melodic idea that is presented and imitated by different voices or instruments.
- Answer: A melodic response to the subject, typically in a different voice or instrument.
- Countersubject: A secondary melodic idea that accompanies the subject or answer.
- Episode: A passage that occurs between statements of the subject or answer.
- Stretto: Overlapping statements of the subject or answer.
- Inversion: A transformation of the subject or answer in which the intervals are reversed.
These contrapuntal devices are used to create intricate and harmonically rich textures in a fugue.
