Fugue

In music, a fugue (/fjuːɡ/ FEWG) is a contrapuntal compositional technique in two or more voices, built on a subject (theme) that is introduced at the beginning in imitation (repetition at different pitches) and recurs frequently in the course of the composition.

The English term fugue originated in the 16th century and is derived from the French word fugue or the Italian fuga. This in turn comes from Latin, also fuga, which is itself related to both fugere ("to flee") and fugare ("to chase"). The adjectival form is fugal. Variants include fughetta (literally, "a small fugue") and fugato (a passage in fugal style within another work that is not a fugue).

A fugue usually has three 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. In the Middle Ages, the term was widely used to denote any works in canonic style; by the Renaissance, it had come to denote specifically imitative works. Since the 17th century, the term fugue has described what is commonly regarded as the most fully developed procedure of imitative counterpoint.

G minor

G minor is a minor scale based on G, consisting of the pitches G, A, B♭, C, D, E♭, and F. For the harmonic minor scale, the F is raised to F♯. Its relative major is B-flat major, and its parallel major is G major.

Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. G minor is one of two flat key signatures that require a sharp for the leading-tone (the other is D minor).

Mozart's use of G minor

G minor has been considered the key through which Wolfgang Amadeus Mozart best expressed sadness and tragedy, and many of his minor key works are in G minor, such as the Piano Quartet No. 1 and the String Quintet in G minor. Though Mozart touched on various minor keys in his symphonies, G minor is the only minor key he used as a main key for his numbered symphonies (No. 25, and the famous No. 40). In the Classical period, symphonies in G minor almost always used four horns, two in G and two in B-flat alto. Another convention of G minor symphonies observed in Mozart's No. 25 was the choice of E-flat major for the slow movement, with other examples including Haydn's No. 39 and Johann Baptist Wanhal's G minor symphony from before 1771 (Bryan Gm1).

Fugue in G minor, BWV 1000

The Fugue in G minor is a musical composition, possibly for the lute, written by Johann Sebastian Bach shortly after he moved from Köthen to Leipzig in 1723.

Today the piece is typically played on the guitar.

Origin

Bach extracted the second movement from his Sonata No. 1 in G minor for solo violin, BWV 1001, written in 1720, and rewrote it; it is not clear that it was intended for the lute. No definitive manuscript version exists today, although there is a contemporary copy in tablature, possibly made by Bach's lutenist friend, Christian Weyrauch.

Fugue in G minor, BWV 578

Fugue in G minor, BWV 578, "Little" (popularly known as the "Little Fugue"), is a piece of organ music written by Johann Sebastian Bach during his years at Arnstadt (1703–1707). It is one of Bach's best known fugues and has been arranged for other voices, including an orchestral version by Leopold Stokowski.

Early editors of Bach's work attached this title to distinguish it from the later Great Fantasia and Fugue in G minor, BWV 542, which is longer in duration.

Score

The fugue's four-and-a-half measure subject is one of Bach's most recognizable tunes. The fugue is in four voices. During the episodes, Bach uses one of Arcangelo Corelli's most famous techniques: imitation between two voices on an eighth note upbeat figure that first leaps up a fourth and then falls back down one step at a time.
