2 Understanding Bah, 6, Bah Network UK 2011 The Impliations of Bah s Introdution of New Fugal Tehniques and Proedures in The Well-Tempered Clavier Book Two YO TOMITA A omparative study of the two parts of The Well-Tempered Clavier reveals that the differenes between them are more striking than their superfiial similarities. One of the most signifiant differenes is the stylisti diversity, the oexistene of old and new styles, of The Well-Tempered Clavier Book II (WTC II). It is tempting to ask whether this diversity is related to Bah s deision to write a seond set of 24 preludes and fugues after omposing the first volume in 1722, when he was not apparently planning to write the Zweyter Theil. 1 If Bah did have a partiular reason for ompiling this seond set in the late 1730s, it ould have been to use all the stylisti devies he knew. Careful examination of Bah s other ompositions of the late 1730s and early 40s, as well as those of his peers and sons, may reveal a glimpse of the truth. It is ertainly an interesting issue to pursue. The ontext of suh a hypothesis seems lear and plausible, and it ould have enormous onsequene for our understanding of Bah the man as well as of his works. Bah was on good terms with many prominent musiians of his time, and his honorary appointment as Compositeur to the Royal Court Orhestra in Dresden in November 1736 must have reated further opportunities for him to beome familiar with the musi of both the new and old styles. His awareness of the latter the styles pratised in old Catholi liturgial musi, renowned for their serenity and durability is ruial, as is shown not only in the opies Bah made of works by Palestrina, Caldara and Bassani, but also in the lear influene of these on his own ompositions. 2 However, finding examples of new and old in WTC II and seeking their models in the works of Bah s ontemporaries is not the subjet of this paper, for 1 In the absene of the title-page in Bah s autograph (GB-Lbl, Add. MS 35021), a fair opy in the hand of Johann Christoph Altnikol dated 1744 (D-B, Mus. Ms. Bah P 430) is urrently onsidered both the earliest and most reliable desription of the olletion, whih reads: Des Wohltemperirten Claviers, Zweyter Theil, besthehend in Præludien und Fugen durh alle Tone und Semitonien verfertiget von Johann Sebastian Bah See Christoph Wolff, Der stile antio in der Musik Johann Sebastian Bahs. Studien zu Bahs Spätwerk (Wiesbaden: Franz Steiner, 1968), esp. p. 36 f.

3 36 Yo Tomita it is unlikely that a disussion of styles at the level of material would on its own reveal muh useful information about Bah s ompositional approahes and ideals. Instead, I am going to onentrate on the mehanisms of his fugue writing, namely the tehniques and proedures that made the fugues of WTC II more eloquent and powerful than those of The Well-Tempered Clavier Book I (WTC I), through the disussion of six seleted fugues. I hope that this disussion will shed light on the stylisti features of Bah s ompositions in this period. Bah s new fugal tehniques and proedures So what is new in the fugues of WTC II and what truly stands out Most obviously prominent are the instanes where Bah has emphasised a fugal subjet by thikening its texture, for example, treating it as a double entry in thirds and sixths (as in Fugues in G minor and B minor, shown in Examples 1 2 respetively) or reating a simultaneous entry against its inversion (as in Fugue in D minor, shown in Example 3). These instanes tend to our at the limax of a dramati fugal disourse. Bah did not use this tehnique in WTC I. I shall return to this point and examine it more losely. & b b b b ΠJ J J Πj # (a) 6 & b b b b j n j n Πj n # # (b) 59 & b b b b b b j J 62 & b b b b b b b b b j b b J. b n b b b j J b Example 1: Fugue in G minor: (a) opening; (b) bars 59 64

Example 3: Fugue in D minor: (a) opening; (b) ending Another extraordinary feature, whih is less obvious but more impressive tehnially, is the flexible use of double and triple ounterpoint in whih voies are interhanged at several intervals, namely the otave, tenth or twelfth (as in the fugues in G minor and B major). This not only permits doubled entries and strettos but also supplies new and exiting harmoni flavours, espeially the seondary seventh hord, as shown in Example 4. Note that the interhange at the twelfth provides 9 8 suspensions in almost every bar (bb. 29, 30 and 32). The

5 38 Yo Tomita interhange of the tenth and doubling in thirds, 3 as already shown in Example 1b, likewise provides spikily oloured seondary seventh hords in every bar. This fugue has double exhanges in both the subjet and the ountersubjet. From a tehnial point of view, however, the interhange at the tenth is rarely used, espeially in double fugues, owing to its omplexity. 4 For those who know the tehnial diffiulties assoiated with the use of this tehnique, this fugue is a partiularly powerful demonstration of Bah s ompositional skills. 28 & b b n Œ J b b # n n n J n n J. n # # n n Example 4: Fugue in G minor: bars The interhange at the twelfth, a tehnique whih is used more widely in WTC II (e.g. Fugues in C minor, G minor and B major), omes in between the other two intervals. 5 There are some limited instanes of interhange tehniques used in WTC I, 6 but not to the extent of the great tehnial and expressive possibilities explored here. It is logial, therefore, that we find Bah exploring the interhange at the tenth and twelfth further in his next fugue projet, The Art of Fugue (BWV 1080). 7 Bah s fugal onstrutions or proedures have other interesting features whih ontribute diretly to the fugal disourse. In WTC II, there is a greater variety, from very free to very strit. This may seem ontraditory given that the fugues of WTC II explore fewer varieties in terms of the number of voies used, being in three and four parts only, whereas WTC I inludes a two-part fugue as well as two five-part fugues. However, Clavierübung III and the Goldberg Variations, the ompositions Bah was working on alongside WTC II in the late 1730s, show that he seems to have limited himself to finding well-hosen varieties within self- 3 Employing the interhange at the tenth at the same time as at the otave produes doubling in thirds. Interhange at the otave is of ourse always possible. 4 Certainly it is not easy to find an example of this kind, as Rihard Stöhr omments. See Rihard Stöhr, Musikalishe Formenlehre, 4th edn. (Leipzig: Siegel, 1921), p. 46. I am very grateful to Nobuaki Ebata for pointing this out. As will be disussed later (see note 25), Mattheson apparently took the same view. 5 Compositionally speaking, the interhange at the twelfth is not as diffiult as that at the tenth beause as long as two voies move in parallel thirds, the interhange at the twelfth results in parallel thirds as well. I am again grateful to Nobuaki Ebata for the same. 6 The exposition of the Fugue in A minor of WTC I, for example, demonstrates how the idea of interhange at otave and twelfth is treated in a limited way in omparison with the examples found in WTC II. There are also other, less prominent examples in WTC I: Fugue in A major (in episode only, bb. 11, 14 and 19) and Prelude in E major (bb. 46 f.). 7 This theory is supported by the watermark evidene, namely that Bah s autograph manusript of The Art of Fugue (D-B, Mus. ms. Bah P 200) uses the same paper as the two movements of WTC II that Bah ompleted last in (viz. the preludes and fugues in C and A major).

6 The Impliations of Bah s Introdution of New Fugal Tehniques and Proedures 39 imposed restritions in other words, as might an expert in any other field, he set himself a more diffiult problem to solve. In fat, the rules of WTC were already tight: a prelude-fugue pair must fill the twenty-four slots overing all twelve major and twelve minor keys, and the hosen piees must be arranged in asending order on a hromati sale from C major to B minor, possibly in a sequene of movements that has some (as yet unrevealed) meaning. 8 Thus the lak of variety in the number of voies in fugues ould well be seen as another layer of restrition rather than ompromise. This is ompensated amply by the variety in other respets, whih I believe are fugal tehniques and proedures. Some have very loose but logially proessed proedures (e.g. Fugue in D minor), while others have a very rigid external framework of premeditated artifie (e.g. Fugues in F minor and B minor). The latter is of partiular interest here, as the rigid proedural framework must have been arefully worked out as one of the fundamental ideas of the movement with whih to ahieve the ompositional objetive. Examples of this metiulously pre-planned arhiteture disussed below are the Fugue in F minor, whih exploits two subsidiary subjets with their own expositions, and the Fugue in B minor whih exploits inversion and stretto. Fugue in F minor (BWV 883/2) The Fugue in F minor is the most properly onstruted triple fugue Bah wrote, that is, eah of the three subjets is introdued by its own exposition, and all three are ombined in the final setion. 9 (The losest to this is the Fugue in C minor of WTC I, the onstrution of whih is not as neat and methodial as this example in WTC II; another example is the St Anne fugue of Clavierübung III (BWV 552/2), although this does not present the three subjets simultaneously, hene is more properly alled a double fugue with three distint subjets.) To ompose this kind of fugue, the omposer needs to oneive all three subjets in advane and test the ombination before embarking on writing the fugue properly. For this piee, Bah used three distint melodies as subjets as shown in Example 5: 8 See, for example, Hans Nissen, Der Sinn des Wohltemperierten Klavier II. Teil, Bah- Jahrbuh, 39 ( ), Problems with his approah are disussed in Yo Tomita, Psalm and The Well-Tempered Clavier II: Revisiting the Old Question of Bah s Soure of Inspiration, Bah, 32/1 (2001), It should be noted that Mattheson alls this type of fugue double fugue with three subjets (Doppelfugen mit dreien Subjeten). See Johann Mattheson, Der vollkommene Capellmeister, das ist gründlihe Anzeige aller derjenigen Sahen, die einer wissen, können und vollkommen inne haben muss, der einer Capelle mit Ehren und Nutzen vorstehen will (Hamburg: Christian Herold, 1739), p. 441.

In the episode, the motif explores freedom in a modulating ontext (perhaps representing the third person of the Trinity, the Holy Ghost). Example 5: Three subjets of the Fugue in F minor It is worth noting that similar patterns of three subjets an be found in the triple fugues mentioned above. In all probability, Bah then designed the fugal proedures, as seen in the version we know today: 1. exposition (bb. 1 11) with an episode (bb ) and a redundant entry (bb ), ending in the relative major 2. introdution of the first subsidiary subjet and its exposition (bb. 21 4) with two redundant entries (bb. 23 8) 3. ombination of the two subjets (bb ) with a short episode in the middle 4. introdution of the seond subsidiary subjet and its exposition (bb. 36 9), followed by an extensive episode (bb ) 5. the subjet returns in bar 51 in the subdominant (key), but the next entry in the toni (key) in bar 54 is the expeted entry of the subjet with two subsidiary subjets together, whih is repeated twie (bb. 60f and 65f) and resolved in the toni note rather than hord, as if to express the unity of the Trinity. Why did Bah write this fugue in this way Was it simply to write a proper triple fugue as learly as possible, or did he have a speifi motive for doing so Was it 10 The subsidiary subjet is the term preferred to the more ommonly used term (the seond subjet, et.) used by Joseph Groook in his Fugal Composition: A Guide to the Study of Bah s 48 (Westport: Greenwood, 2003). It is a more preise term to desribe the nature of the devie in the ontext of fugal disourse.

8 The Impliations of Bah s Introdution of New Fugal Tehniques and Proedures 41 somehow related to the trinitarian symbolism expressed in the key-signature, F minor with its three sharps, 11 or to Butler s laim that the final triple fugue of the Clavierübung III was Bah s response to Mattheson s publi invitation to write double fugues with three subjets 12 Do the 70 bars of musial text have anything to do with the fat that this fugue was no. 14 of the olletion 13 These questions are unonneted but new evidene may reveal that one or more is an important piee of the jigsaw. In any event, having produed a perfet example of the triple fugue in WTC II, Bah s next hallenge was to write a great quadruple fugue, whih he did in The Art of Fugue. Fugue in B minor (BWV 881/2) Moving on to the next example, Fugue in B minor of WTC II is also strutured learly and methodially but in a different way from the F -minor fugue examined above. The primary tehniques used in this fugue are inversion and stretto, and on this oasion, Bah deided to use these tehniques as the main ideas for devising six logially sequened setions, as follows: 1. exposition of diret subjet (bb. 1 20) 2. stretto of diret subjet (bb ) 3. exposition of inverted subjet (bb ) 4. stretto of inverted subjet (bb ) 5. stretto of diret and inverted subjet (bb ) 6. stretto of diret and inverted subjet, with added thirds and sixths (bb ). The most striking, of ourse, is the last setion where the entries of the subjets are fortified in thirds and sixths, reating a huge dramati effet, as shown in Example 2b. Atually this tehnial possibility is partially visible in the stretto setions, but who ould have predited suh an ending The head of the subjet is the ross figure with the diminished fifth interval in its ore, whih is reminisent of the subjet of the C -minor fugue of WTC I (see 11 Three flats in the key-signature of E major have previously been onsidered to have the Trinitarian assoiation when disussing the Clavierübung III. See, for example, Peter Williams, The Musial Aims of J.S. Bah s Clavierübung III, Ian Bent (ed.), Soure materials and interpretation of musi: a memorial volume to Thurston Dart (London: Stainer & Bell, 1981), pp , at p See Gregory Butler, Der vollkommene Capellmeister as a stimulus to J.S. Bah s late fugal writing, George J. Buelow and Hans Joahim Marx (eds.), New Mattheson Studies (Cambridge University Press, 1983), pp See also David Ledbetter, Bah s Well-tempered Clavier: The 48 Preludes and Fugues (New Haven and London: Yale University Press, 2002), pp. 96 and 355. Certainly Johann Krieger s fugue whih Mattheson quotes in his Der vollkommene Capellmeister, p.442, as his good example (artiges Exempel) ontains fewer varieties than Bah s F -minor fugue. 13 Number symbolism enthusiasts will immediately notie that 14 is the number alphabet for BACH ( ), and 70 is that for either JOH. SEB. BACH or JESUS. See, for example, Harry Hahn, Symbol und Glaube im I.Teil des Wohltemperierten Klaviers von Joh. Seb. Bah. Beitrag zu einer Bedeutungskunde (Wiesbaden: Breitkopf & Härtel, 1973), pp

9 42 Yo Tomita Example 6). The ountersubjet (bb. 5 8) likewise ontains similar voabularies to express bitterness a fall of diminished fourth initially, followed by an asending hromati sale (see Example 2a). Cf. WTC I: Fugue in C minor Example 6: Subjet of Fugue in B minor onsisting of χ motifs In this ontext the riddle anon, BWV 1077, known through a opy whih Bah presented to a theology student Johann Gottlieb Fulde on 15 Otober 1747 (Example 7) may be onsidered. 14 The similarity between this anon and the Fugue in B minor beomes obvious when the solution of this anon is worked out (i.e. the voies are inverted). With the insription Symbolum: Christus Coronabit Cruigeros (Christ will rown ross-bearers), Bah appears to be saying that any theologian worth his salt will understand that the solution to this little musial puzzle lies in turning the tunes upside down. 15 The ombination of the hromati-sale motif and the inversion tehnique produes the symboli meaning of χ (Chi). Can we also assume that Christ s ruifixion is implied in this fugue in WTC II If the number 22 symbolises anything here, the referene to Psalm 22 is perhaps something whih Bah may have had in mind While Elise Crean onsiders the draft of this anon (and indeed all the fourteen anons, BWV 1078) were written after the omposition of the Musial Offering, it is also worth onsidering that the early draft of this anon atually originated around the time when this fugue was written, i.e when the Goldberg Variations were also being ompiled. See Elise Crean, The Fourteen Canons (BWV 1087): Foundation or Culmination A re-evaluation of their position among Bah s late works, Understanding Bah 5 (2010), at Mel Unger, Chiasti Refletion in the B-minor Mass: Lament s Paradoxial Mirror, International Symposium: Understanding Bah s B-minor Mass.

Mills (Belfast: Shool of Musi and Soni Arts, Queen s University Belfast, 2007), pp at See Tomita, Psalm and The Well-Tempered Clavier II. In it the number symbolism of 22 is disussed in onjuntion with the opening theme of the Prelude in B minor of WTC II whih resembles losely with the tune in movement 61a of St Matthew Passion sung by Jesus Eli, Eli lama asabthani referring to Psalm 22. The key of that passage is also in B minor.

Not only is the sequene of setions logial, the effet of the atual fugues is also powerfully dramati. The most interesting thing these examples show is that the methodial struturing of these fugues may be onneted to the deep-rooted purpose of writing them a seret whih is yet to be deoded. The metamorphosis fugues My next examples are those fugues whih employ the subsidiary subjet from halfway through, the appearane of whih is gradually revealed in the fugal disourse. An attentive listener will notie that the appearane of the new subjet is a logial neessity, revealing an important agenda in the omposition. Three fugues in WTC II an be onsidered to belong to this type, Fugues in C minor, G minor and B major.

11 44 Yo Tomita Fugue in C minor (BWV 873/2) The subsidiary subjet (hromati fall) first appears prominently in bar 35 in the soprano, whih is followed by the alto in the following bar and followed again in the bass, the setion being seen effetively as the exposition of this new subjet (see Example 8). It is first ombined with the subjet at bar 48. In hindsight, its appearane was foreast in bar 20 as a modified form of the ountersubjet first heard in bars 2 4 in the bass. 17 An advaned state of metamorphosis may be seen in the soprano in bars 26 28, whih is atually the ountersubjet (albeit heavily distorted at this point) for the inverted subjet but also seen retrospetively as the fragmented diminution of the new subjet. Thus, in essene, the new subjet is a metamorphosis of the old ountersubjet. Countersubjet Entries of Subsidiary Subjet Example 8: Fugue in C minor, indiating the stages of metamorphosis Fugue in G minor (BWV 887/2) The subsidiary subjet (hromati fall then rise) first appears in bar 61 in the soprano (with its ountersubjet in the bass see Example 9). As in the previous example, this entry marks the start of the exposition of the subsidiary subjet, whih ontinues until it appears together with the subjet in bar 97. The announement of the subsidiary subjet in bar 61 is treated in suh a way that it sounds fresh, as if to start exploring new territory; but the new subjet is again based on the ountersubjet first heard in bars 5-7 and a glimpse of metamorphosis is spotted in bar Charles Stewart MaPherson observes the same in A Commentary on Book II of the 48 Preludes and Fugues of Johann Sebastian Bah (London: Novello & Co., 1937), p. 13.

12 The Impliations of Bah s Introdution of New Fugal Tehniques and Proedures 45 Countersubjet Entries of Subsidiary Subjet Example 9: Fugue in G minor, first half, indiating the stages of metamorphosis It is interesting that the subsidiary subjet in these two minor-mode three-part fugues is based on a hromati sale, although not surprising given that their subjets are made up of similar melodi and rhythmi profiles (i.e. eah has a melody made up of diatoni sale with oasional leaps, set in plain and regular rhythm). 18 In terms of motivi shape, the subsidiary subjets are based on the ountersubjets whih are angular and less well-defined. This an be explained by the way they are introdued in the first instane, to assume the role of aompanying the main subjet so as to provide harmoni support. The metamorphosis of the devie from the ountersubjet to the subsidiary subjet an thus be seen as a refinement of melodi material, i.e. to introdue an equally well-defined melody to the ounterpoint. The fugal proedures are also similar: both fugues have expansive opening setions featuring ounter-exposition before the subsidiary subjet is introdued. They are also written in rare and related keys (with four and five sharps in their respetive key-signatures), and were perhaps omposed around the same time. 19 Everything indiates that Bah was experimenting with a speifi model of fugal proedure at the time. 18 The use of hromati passage in the ounter-theme in double fugues is disussed by Mattheson, p. 434, as devie whih gives the greatest ontrast (grosten Untershied). 19 Both movements were omposed around 1740, but beause the autograph of Prelude and Fugue in C minor is lost, it is diffiult to engage with soure-ritial disussion to establish a more preise hronology. See Yo Tomita, J.S. Bah s Well-Tempered Clavier, Book II: A Study of its Aim, Historial Signifiane and Compiling Proess, PhD diss., University of Leeds, 1990, pp. 46 f, and Rihard Jones, Stages in the development of Bah s The Well-Tempered Clavier II, The Musial Times, 132/1783 (Sep. 1991),

13 46 Yo Tomita Fugue in B major (BWV 892/2) The subsidiary subjet (floating quavers) first appears in bar 28 in the soprano as a freshly introdued subjet. In terms of material, however, it effetively replaes two ountersubjets used in the exposition, as it an be traed to the odetta figure in bar 9 and part of the seond ountersubjet in bar 11, both of whih are repeated in the rest of the exposition. Thus the subsidiary subjet is again seen as a metamorphosis of the earlier material of lesser prominene. Subsidiary Subjet Example 10: Fugue in B major, opening setion, indiating the signs of metamorphosis The fugal proedure is quite different from the preeding examples in a number of respets. First, this is a four-part rather than three-part fugue. This usually means that the exposition takes longer to omplete, although, interestingly, this is not the ase here as we shall see below. Seondly, the melodi ideas employed in the subjet and subsidiary subjet are very different: in the B- major fugue, the subjet is slow-moving in leaping minims, while the subsidiary subjet is based on a diatoni rather than hromati sale, and explores an interhange at the twelfth with the main subjet. Thirdly, the new subjet emerges from the synthesis of two ountersubjets rather than the gradual metamorphosis of one ountersubjet. Fourthly, the metamorphosis takes plae very swiftly at a quarter of the way through the fugue (bar 27 of the total of 104 bars = 25 per ent), in ontrast to the slow-proessing metamorphosis whih is finally aomplished almost halfway through the three-part fugues (Fugue in C minor (bar 35 of the total of 71 bars = 49 per ent) and Fugue in G minor (bar 61 of the total of 143 bars = 43 per ent)). Fifthly and finally, when introdued for the first time at bar 28, the new subjet of the B-major fugue does not have its own exposition but appears as the ountersubjet of the subjet. The effet of the last two points is one of resetting and restarting the fugal proedure. For these reasons, the fugal proedure for the B-major fugue needs to be distinguished from the preeding examples, although the basi priniple of metamorphosis is still present. Yet it seems signifiant that in all three examples disussed above, the metamorphosis theme appears in the aomplished form for the first time in the soprano, as if being eremoniously revealed. There may be a partiular reason for this ompositional hoie, suh as a female voie that played a divine role in

14 The Impliations of Bah s Introdution of New Fugal Tehniques and Proedures 47 the theologial onvention of Bah s time. 20 It is worth noting that a similar metamorphosis idea is also found in the seond movement of the Trio Sonata in Musial Offering (BWV 1079). The hromatially-oloured new subjet with expressive sigh motif is first pronouned in the flute part (top part of the texture) in bar 48, whih has evolved from a rather plain ountersubjet heard in the exposition (bars 11 f), as shown in Example (a) (b) Example 11: Extrats from Allegro from the Trio Sonata in Musial Offering (BWV 1079): (a) bars 10 19; (b) bars I am grateful to Professor Ruth HaCohen for pointing out this possibility. The subjet of sared femininity was explored by Wendy Heller in her paper Mary Sings: searhing for the Feminine in Bah s World read at the Fifth Dialogue Meeting in Edinburgh on 13 August 2011, whih will appear in Understanding Bah, 7 (2012). 21 In Exploring the Limits: the Tonal, the Gestural, and the Allegorial in Bah s Musial Offering, Understanding Bah, 1 (2006), at 37 8, Ruth HaCohen relates the signifiane of the flute part of this movement to a politial game Bah was playing with Frederik the Great.

15 48 Yo Tomita Assessment What then was Bah trying to ahieve with the metamorphosis idea From a strutural perspetive, these fugues are dissimilar to the methodially onstruted fugues examined earlier. The metamorphosis is suh a subtle idea that it annot have been fully pre-planned; it is more likely that Bah had only a vague idea of how he might be writing the metamorphosis fugues. The loose but luid and logial flow of these fugues seems like a masterly at of improvisation. 22 The sheer expressive power of Bah s fugal style thus appears to be the result of a marriage between metiulously well-organised ideas and free improvisation, whih somehow helped Bah to write more dramati, more profound fugues for WTC II. It seems signifiant, therefore, that a similar pattern of free and strit is also found in the two surviving Lute works (BWV 997 and 998), whih inidentally are ontemporary with WTC II. 23 Is it merely a oinidene that these foreshadow the two ontrasting Rierars of Musial Offering to be omposed a few years later How did Bah ome to aquire these new fugal tehniques and proedures What motivated him to adopt these new ompositional approahes Bah and rhetori In his artile Fugue and Rhetori, Gregory Butler explores how the priniple behind the omposition of fugues is governed by rhetori. Aording to Butler, the onfutatio or refutatio, a middle setion in whih the opposition to the propositio is to be presented and resolved, is partiularly important in the rhetorial dispositio sheme. In his Der vollkommene Capellmeister of 1739, Mattheson refers to this aspet as an important area of musial interest that involves suh devies as dissonanes, synopations, themati fragmentation, and inversion, when disussing the onfutatio: The onfutatio is a resolution of the objetions and may be expressed in musi either through suspensions or also through the introdution and refutation of strange-seeming passages. For it is just by means of these elements of opposition, provided that they are deliberately rendered prominent, that the delight of the ear is strengthened and everything in the nature of dissonanes and synopations whih may strike the ear is settled and resolved Mihael Marissen observes the same tehnique being used in Bah s early voal works, giving the three-part fugal horus Es ist der alte Bund of BWV 106 as an example: here the ountersubjet Mensh, du mußt sterben gradually metamorphoses, in the end, into the shape of the opening motif from the horale Herzlih tut mih verlangen, a melodi shape also adopted from the outset by the non-fugal soprano line for Ja komm, Herr Jesu, komm in this same movement. While this metamorphosis tehnique may not be entirely new to Bah at the time of WTC II, it is still a noteworthy features of keyboard fugues of WTC II, as it was never being used in WTC I.

16 The Impliations of Bah s Introdution of New Fugal Tehniques and Proedures 49 What we have found in the G-minor Fugue the lashing dissonane resulting from suspension figures, and the use of seondary seventh hords on the strong beat, whih was introdued by the voie interhange at tenth and twelfth, reating a suession of nervous moments fits this sene beautifully. The tatful use of inversions found in the B -minor fugue also belongs to this ategory. It is worth adding that in the same work Mattheson also disusses the invertible ounterpoint at otave, tenth and twelfth, the middle of whih is desribed most diffiult (allershwersten): Beause the omposition of ounterpoint at the tenth tends to be most diffiult, I want to plae yet one more illustration here, and at the same time show how it looks when the third voie goes with one of the others in like steps. Why it again is generally so diffiult to use suspensions here is easy to judge from the fat that aording to the above numerial ordering of intervals, no single dissonane an be resolved naturally on inversion: unless one perhaps were to permit the seond to go to the third, afterwards in the evolution the ninth and otave ome out of it. 25 Moving loser to the final setion of the fugue, there is also a speifi issue in the rhetorial dispositio sheme. Butler observes this to be stretto, 26 the piling up of entries of the theme, whih has lose parallels with the proedure adopted by rhetoriians in onfirmatio. Again it has already been observed in the B -minor as well as the fugue in G minor (quasi stretto found in bb ) that Bah regularly resorts to using strettos to inrease musial tension. In fat, the simultaneous appearane of the subjet an be seen as a more powerful version of the devie that an be used in onfirmatio. In his exellent monograph on the WTC published by Yale University Press in 2002, Ledbetter observes that there are a number of fugue subjets in WTC II whih losely resemble Mattheson s examples of rhythms, namely spondee (two long syllables a Greek term meaning libation, or solemn offering ; f. Fugue in B major), 27 tribrah (three short syllables) (Fugues in C minor /G minor) and bahius (a short and two longs; f. Fugue in G minor), 28 inidentally all the fugues I have speifially hosen for this paper (see Example 12). What do these examples show If these rhythms are deliberate, what did Bah want to ahieve To me this is yet another example of Bah responding to his ontemporaries theoretial writings on how to ompose exellent fugues, whih losely reflet the rhetorial priniples of musial omposition disussed most reently by Mattheson, one of the most powerful and progressive writers of the time. Marpurg s extensive iting of the WTC II in his Abhandlung von der Fuge ( ) appears to testify that Bah was writing the exemplary fugues of his 25 Mattheson, p Trans. Ernest C.

The oft-ited infamous attak of Sheibe, desribing Bah as a omposer with no sympathy for amenity (Annehmlihkeit) who takes away the natural element in his piees by giving them a turgid (shwülstig) and onfused style, 29 seems partiularly relevant here. To me the metamorphosis fugues an be seen as Bah s response, demonstrating his ability to write luid and powerful fugues. Doubtless many other ontemporary referenes whih ould teah us about Bah s approah to WTC II have so far esaped our notie. Let us ontinue to engage losely with Bah s ontemporaries, in partiular Mattheson, Sheibe, and Marpurg, so as to gain further knowledge of Bah s mastery of fugal writing. J J J 29 NBR, p. 338.
