FUGUE (See also:Lat. fuga, See also:flight)  , in See also:music, the mutual "pursuit" of voices or parts . It was, up to the end of the 16th See also:century, if not later, the name applied to two See also:art-forms . (A) Fuga ligata was the exact See also:reproduction by one or more voices of the statement of a leading See also:part . The reproducing See also:voice (comes) was seldom if ever written out, for all See also:differences between it and the See also:dux were rigidly systematic; e.g. it was an exact See also:inversion, or exactly twice as slow, or to be sung backwards, &c . &c . Hence, a See also:rule or See also:canon was given, often in enigmatic See also:form, by which the comes was deduced from the dux: and so the See also:term canon became the appropriate name for the form itself, and is still retained . (B) A See also:composition in which the canonic See also:style was cultivated without canonic restriction was, in the 16th century, called fuga ricercata or simply a ricercare, a term which is still used by See also:Bach as a See also:title for the fugues in Das musikalische Opfer . The whole conception of See also:fugue, rightly understood, is one of the most important in music, and the reasons why some contrapuntal compositions are called fugues, while others are not, are so trivial, technically as well as aesthetically, that we have II preferred to treat the subject separately under the See also:general heading of CONTRAPUNTAL FORMS, reserving only technical terms for See also:definition here . (i.) If in the beginning or " exposition " the material with which the opening voice accompanies the See also:answer is faithfully reproduced as the See also:accompaniment to subsequent entries of the subject, it is called a countersubject (see See also:COUNTERPOINT, under sub-heading See also:Double Counterpoint) . Obviously the See also:process may be carried further, the first countersubject going on to a second when the subject enters in the third part and so on . The term is also applied to new subjects appearing later in the fugue in See also:combination (immediate or destined) with the See also:original subject . See also:Cherubini, holding the See also:doctrine that a fugue cannot have more than one subject, insists on applying the term to the less prominent of the subjects of what are commonly called double fugues, i.e. fugues which begin with two parts and two subjects simultaneously, and so also with triple and quadruple fugues .

(ii.) Episodes are passages separating the entries of the subject.' Episodes are usually See also:

developed from the material of the subject and countersubjects; they are very rarely See also:independent, but then conspicuously so . (iii.) Stretto, the overlapping of subject and answer, is a resource the possibilities of which may be exemplified by the setting of the words omnes generationes in Bach's Magnificat (see BACH) . (iv.) The distinction between real and tonal fugue, which is still sometimes treated as a thing of See also:great See also:historical and technical importance, is really a See also:mere detail resulting from the fact that a violent oscillation between the keys of tonic and dominant is no part of the See also:function of a fugal exposition, so that the answer is (especially in its first notes and in points that tend to shift the See also:key) not so much a transposition of the subject to the key of the dominant as an See also:adaptation of it from the tonic part to the dominant part of the See also:scale, or See also:vice versa; in See also:short, the answer is as far as possible on the dominant, not in the dominant . The modifications this principle produces in the answer (which have been happily described as resembling " fore-shortening ") are the only distinctive marks of tonal fugue; and the See also:text-books are See also:half filled with the See also:attempt to reduce them from matters of See also:ear to rules of thumb, which rules, however, have the merit (unusual in those of the See also:academic fugue) of being founded on observation of the practice of great masters . But the same principle as often as not produces answers that are exact trans-positions of the subject; and so the only See also:kind of real fugue (i.e. fugue with an exact answer) that could rightly be contrasted with tonal fugue would be that in which the answer ought to be tonal but is not . It must be admitted that tonal answers are rare in the modal music of the 16th century, though their melodic principles are of yet earlier date; still, though tonal fugue does not become usual until well on in the 17th century, the See also:idea that it is a See also:separate See also:species is manifestly absurd, unless the term simply means " fugue in See also:modern tonality or key," whatever the answer may be . The term " answer " is usually reserved for those entries of the subject that are placed in what may be called the " complementary " position of the scale, whether they are " tonally " modified or not . Thus the See also:order of entries in the exposition of the first fugue of the Wohltemp . Klay. is subject, answer, answer, subject; a departure from the usual rule according to which subject and answer are strictly alternate in the exposition . In conclusion we may remind the reader of the most accurate as well as the most vivid description ever given of the essentials of a fugue, in the famous lines in See also:Paradise Lost, See also:book xi . " His volant See also:touch, See also:Instinct through all proportions, See also:low and high, Fled and pursued transverse the resonant fugue." It is hard to realize that this description of See also:organ-music was written in no classical See also:period of instrumental polyphony, but just half-way between the See also:death of See also:Frescobaldi and the See also:birth 'An See also:episode occurring during the exposition is sometimes called codetta, a distinction the uselessness of which at once appears on an See also:analysis of Bach's and fugue in the Wohitemp . Klay .

(the term codetta is more correctly applied to notes filling in a See also:

gap between subject and its first answer, but such a gap is rare in See also:good examples).of Bach . Every word is a definition, both retrospective and prophetic; and in " transverse " we see all that See also:Sir See also:Frederick See also:Gore See also:Ouseley expresses in his popular distinction between the " perpendicular " or homophonic style in which See also:harmony is built up in chords, and the " See also:horizontal " or polyphonic style in which it is See also:woven in threads of independent See also:melody .
