In music, a fugue is a contrapuntal compositional technique in more than two voices, built on a subject that is introduced at the beginning in imitation and which recurs frequently in the course of the composition. It is not to be confused with a fuguing tune, which is a style of song popularized by and mostly limited to early American music and West Gallery music. A fugue usually has three main sections: an exposition, a development and a final entry that contains the return of the subject in the fugue's tonic key. Some fugues have a recapitulation.

The Art of Fugue, or The Art of the Fugue, BWV 1080, is an incomplete musical work of unspecified instrumentation by Johann Sebastian Bach. Written in the last decade of his life, The Art of Fugue is the culmination of Bach's experimentation with monothematic instrumental works.

In cryptography, a preimage attack on cryptographic hash functions tries to find a message that has a specific hash value. A cryptographic hash function should resist attacks on its preimage.
Salt is a dietary mineral, used for flavoring and preservation.

The Grosse Fuge, Op. 133, is a single-movement composition for string quartet by Ludwig van Beethoven. An immense double fugue, it was universally condemned by contemporary music critics. A reviewer writing for the Allgemeine musikalische Zeitung in 1826 described the fugue as "incomprehensible, like Chinese" and "a confusion of Babel". However, critical opinion of the work has risen steadily since the early 20th century and it is now considered among Beethoven's greatest achievements. Igor Stravinsky described it as "an absolutely contemporary piece of music that will be contemporary forever."

Modulation is the process of varying one or more properties of a high-frequency periodic waveform.
Fugue is a cryptographic hash function submitted by IBM to the NIST hash function competition. It was designed by Shai Halevi, William E. Hall, and Charanjit S. Jutla. Fugue takes an arbitrary-length message and compresses it down to a fixed bit-length. The hash functions for the different output lengths are called Fugue-224, Fugue-256, Fugue-384 and Fugue-512. The authors also describe a parametrized version of Fugue. A weak version of Fugue-256 is also described using this parameterized version.
