What is a Real Answer (Fugue)?

A real answer in a fugue is a type of fugue answer in which the subject is repeated exactly, interval for interval, in another voice—usually at the dominant key. Every note and interval of the subject is preserved without alteration, making it a precise transposition of the original theme.

Real answers are most commonly used in strict or tonal fugues, where the imitation of the subject needs to be exact to maintain clarity and structural balance. Because the intervals are preserved, the real answer provides a strong sense of symmetry and consistency between voices.

The real answer helps establish the tonal framework of the fugue and supports the contrapuntal texture. Composers such as Johann Sebastian Bach often used real answers in the early stages of a fugue to present the subject clearly in multiple voices before moving into more elaborate development and episodes.
