Extract

The extraordinary dissemination of the Parisian repertory, resulting in its establishment in the thirteenth century as a kind of ‘Classical’ style (and later as an ars antiqua), was greatly abetted – if not made possible in the fist place – by what may have been an exclusively written mode of transmission. This is apparently the earliest body of polyphony to have been conceived, preserved and circulated entirely in writing. Equally important for the impact of the music of Paris, however, is the fact that it spawned a didactic tradition. It provided the foundation for a group of treatises that were the first to elucidate an already existing polyphonic repertory. Rather than instructing the singer how to generate polyphonic embellishments of plainchant ex tempore, these theoretical texts provided him with the information he needed to transform the written symbols in the manuscript before him into sounding music consistent with the intentions of the composer (or, at least, of the scribe), and they offered guidance to the organista wishing to create other works in a similar idiom. To be sure, these treaties did not transmit the Paris style intact.

41 Waite, , The Rhythm of Twelfth-Century Polyphony, p. 17Google Scholar. It may be that the anonymous writer, seeing Garlandia's remark that organum in speciali can be considered in a twofold manner, and supposing per se and cum alio to be distinct types, set out to produce a description of organum cum alio for his own purposes, doing so by taking the organum non rectum passage and altering it by substituting ‘cum alio’ for ‘non rectum’ and removing each instance of the word ‘non’.

42 Reimer, , Johannes de Garlandia, De mensurabili musica, i, p. 35 (Chap. i, 4 )Google Scholar: ‘Discantus est aliquorum diversorum cantuum sonantia secundum modum et secundum aequipollentis sui aequipollentiam’.

43 Ibid., i, pp. 35–6 (Chap. i, 5): ‘Sed quia in huiusmodi discantu consistit mancries sive modus, in primis videndum est, quid sit modus sive maneries, et de specicbus ipsius modi sive maneriei et gratia huiusmodi maneriei ac specierum eius plura alia videbimus’.

44 Ibid., i, pp. 74–5 (Chap, xi, 3): ‘Unde discantus est aliquorum diversorum cantuum sonantia secundum modum et secundum aequipollentis sui aequipollentiam per concordantiam’.

45 Ibid., i, p. 37 (Chap. i. 16–17).

46 See. for example, Ibid., i. p. 88 (Chap. xii, 5: the redefinition of ‘punctus’), and pp. 37–8 (Chap, i, 22: the definition of ‘tempus’). In fact, Garlandia has already used ‘modus rectus’ in passing in its broader sense, in connection with the interpretation offigurae imperfectae in discantus; Ibid., i, p. 51 (Chap, iii, 20).

47 Ibid., i, p. 38 (Chap, i, 27). See also Ibid., p. 36 (Chap, i, 7) and Discantuspositio vulgaris, in Cserba. ed., Hiemnymus de Moravia O.P., Tractatus de musica, p. 190, 11. 5–8.

48 Even when a ligature has the same values in two different modes, the actual ‘measure’ (in a more recent sense of the term) may be different. Modes 1 and 2 both include the values brevis recta-longa recta, expressed in notation as a binaria; in the first mode, however, the long falls at the beginning of the ternary ‘beat’ and the breve functions as an ‘upbeat’, while in the second mode it is the breve that falls on the ‘beat’.

49 Compare the views of Reckow, Fritz in Der Musiktraktat des Anonymus 4, ii, p. 34Google Scholar (in which he sees Chap, VII as one in which Anonymous iv has ‘zwei ofiensichtlich unvereinbare Rhythmisierungsmethoden nebeneinandergestellt’) and p. 62 (in which he affirms the ‘seltsame Gegensatz’ and ‘der grundsatzliche Widerspruch’ between the different parts of the chapter); also those of Ernest Sanders in ‘Consonance and Rhythm’, p. 270, who argues that ‘[Anonymous iv] and modern scholars have expanded or misunderstood Garlandia's rule’.

51 Ibid., i, pp. 84, 1. 14– p. 85, 1. 17.

52 Ibid., i, p. 85, 11. 18–22: “Et iuxta septem dona spiritus sancti est Septimus modus nobilissimus et dignissimus, magis voluntarius et placens. Et iste modus est modus permixtus et communis et est de omnibus duobus supradictis et de omnibus tribus et de omnibus quatuor etc. Et proprie loquendo denominatur organum purum et nobile etc’ Wolf Frobenius recognised the relationship between Anonymous iv's seventh mode and Garlandia's modus non rectus (‘Modus (Rhythmische)’, Handwörterbuch, pp. 4–5), but accepts Reckow's view of the latter and of the role of the principle of consonance in generating its rhythmic flow.

53 This is preceded by material on the performance of rests and on the consonances, topics common to both copula and organum in speciali; Reckow, , Der Musiktraktat des Anonymus 4, i, p. 85, 1. 27–p. 86, 1. 12Google Scholar.

54 This is further confirmed by Anonymous iv's concluding remarks on the irregular modes; Ibid., i, p. 85, ll 23–7. Compare Reckow's opposing view inIbid., ii, pp. 29–30.

In a remarkably similar manner the discussion of verse types by the grammarian Johannes de Garlandia represents a synthesis of a broader practice, lines of rhymed poetry being classified as either iambic or spondaic according to whether the penultimate syllable is long or short; see Lawler, T., ed. and trans., The ‘Parisiana poetria’ of John of Garland (New Haven, 1974), pp. 160–1, 265Google Scholar.

H., ‘Duple Rhythm and Alternate Third Mode in the 13th Century’, Journal of the American Musicological Society, 15 (1962), pp. 282–6CrossRefGoogle Scholar, none of which accounts entirely satisfactorily for how and why the modal system came to take the form it did, or, indeed, for why the beginnings of a Western rhythmic language came to be conceived in ‘modal’ terms at all. In a future paper I hope to offer a hypothetical model describing the origins and evolution of modal rhythm.

70 Compare the observation by Anonymous iv that the mode could change during the course of a single phrase, ‘sometimes with the help of rests, sometimes without it’, a procedure that he calls ‘admixture’; Reckow, , Der Musiktraktat des Anonymus 4, i, p. 22, ll. 22–4Google Scholar: ‘Et nota, quod quandoque fiunt admixtiones mediante pausatione, quandoque sine, quod videtur esse et non esse.’

71 Compare the states of Alleluia, Nativitas in Florence plut. 29.1, fol. 130r (in which only the discantus phrases are concordant) and Berlin lat. 4° 523, fol. Av. In the latter the ternaria that introduces the copula phrase is drawn as a single long with somewhat elongated head followed by a binaria. a reading that bears an intriguing resemblance to the copula ligata described in Franco of Cologne, Ars cantus mensurabilis, ed. Reaney, and Gilles, , pp. 75–6 (Chap, XII, 3–5)Google Scholar. The quaternaria in the final phrase of the Berlin text is drawn cum opposita proprietate while the final binaria is written sine proprietate and with the first note elongated; see the facs. in Roesner, ‘The Performance of Parisian Organum’, p. 181.

72 Indeed, it must not be assumed that Garlandia based his classification of polyphonic idioms on the repertory of responsorial chant settings that we tend to associate with the word ‘organum’. His classification appears to stand apart from considerations of genre, ignoring as it does such factors as text setting and the presence or absence of a cantus prius factus (see note 32, above, and the careful distinction made by Reckow between Garlandia's treatment of ‘Satz’ and, for example, Grocheio's description of a ‘Gattung’, in ‘Das Organum’, pp. 435–6). Anonymous iv indirectly supports this conclusion when he mentions conducti ‘in quibus continentur puncta finalia organi’; Reckow, , Der Musiktraktat des Anonymus 4, i, p. 82, ll. 12–14Google Scholar. He cites two specific conducti in this regard, Salvatoris hodie and Relegentur ab area, both of which have melismatic caudae with elaborate currentes flourishes against a sustained tone in another voice. (These conducti are found, among other places, in Wolfenbüttel 628 Helmst., fols. 95r–96v and 96v–98r, at the beginning of the conductus collection that makes up fascicle ix of the manuscript; on the striking fact that these and other works cited by Anonymous iv occur in Wolfenbüttel 628 at major points of division in the collection, see Roesner, E. H., ‘The Origins of W 1,’ Journal of the American Musicotogical Society, 29 (1976), pp. 379–80Google Scholar.) But it is not inconceivable that Anonymous iv had other pieces in mind as well when he made his allusion to conducti with sustained-tone passages. In Wolfenbüttel 628 Salvatoris hodie, Relegentur ab area and two other conducti are followed by three Benedicamus domino organa in sustained-tone style (fols. 103v–104v ), and then, after a Gloria paraphrase, Gloria in excelsis deo redemptori meo, by a fourth (fols. 105v–106r), also in organumpurum. Friedrich Ludwig regarded these four works as supplements to the collection of Office organa in fascicle in of the manuscript (Repertorium organorum recentioris et motetorum vetustissimi stili, i/l (Halle, 1910), p. 40)Google Scholar, and indeed the first three are found in Florence plut. 29.1 among the Office settings, and in Wolfenbüttel 1099 at the end of the organum collection, if not directly appended to the Office pieces. But their placement in Wolfenbüttel 628 among the conducti of fascicle ix seems odd; the same scribe copied both these works and the organa in fascicle m, and there would have been ample room for the four Benedicamus domino settings in the organum collection (which was copied into a ternio instead of the more customary quaternio because there were not enough Office pieces to fill a gathering of the standard size). It appears more likely, then, that the four Benedicamus domino pieces belong with fascicle ix, and that in the institution for which Wolfenbüttel 628 was copied, at least, they were intended to be used with the conducti. One of the conducti preceding them in the fascicle, Naturas deus regulis (fols. 98v–101r), concludes its third strophe with a caudaon the words ‘Benedicamus domino’, a musical and textual refrain that occurs at the ends of both strophes 2 and 3 in the copy in Florence plut. 29.1, fols. 211v–214r and 286v–287v, and at the end of strophe 2 only in the redactions in Wolfenbüttel 1099, fols. 96r–99r, and Madrid, Biblioteca National, MS 20486, fols. 107r–109v (strophe 3 is not included in these two copies). This refrain on ‘Benedicamus domino’ recurs in Wolfenbüttel 628, moreover, in the copy of Leniter ex merito on fol. 16r–16v, but not in the redaction of the same piece on fols. 81v–82r. Furthermore, the lower voice of this refrain cauda incorporates a segment of plainchant. (On this and similar situations see Bukofzer, M. F., ‘Interrelations between Conductus and Clausula’, Annales Musicologiques, 1 (1953), pp. 7688.)Google Scholar I suspect that the four organa were intended to function in a manner similar to this refrain, to convert liturgically flexible conducti into more clearly defined Benedicamus domino substitutes through the addition of a ‘Benedicamus domino’ refrain — in these instances, one conceived in organum purum. These refrains could have been applied to any conductus in the manuscript with a text suitable for use as a Benedicamus substitute, and their use would produce works corresponding closely with the description by Anonymous iv cited above. On the relationship between the Benedicamus domino and the conductus see esp. Arlt, W., Ein Festoffizium des Mittelalters aus Beauvais in seiner liturgischen undmusikalischen Bedeutung, 2 vols.

75 See Anonymous iv's interesting observation that the sixth mode can end with either a breve or a long; Reckow, , Der Musiktraktat des Anonymus 4, i. p. 33. 1. 15 – p. 34. 1. 19Google Scholar.

77 Ibid., i, p. 86, ll. 19–22: ‘Item omnis punctus ultimus erit longus et concordans. Item omnis punctus paenultimus ante longam pausationem sicut in fine puncti vel clausulae est longus. Item omnis punctus paenultimus similitudinarie perceptus longus per modum. sive fuerit concordans sive non.’

78 The St Emmeram Anonymous, who shares Anonymous iv's second rule, offers a corrupt — or, at least, modified — version of his rule 3: ‘whatever is notated as a long in the manner of organum before a perfect concord is said to be long’; Sowa, , ed., Ein anonymer glossierter Mensuraltraktat 1279, p. 130, ll. 34–5Google Scholar (‘quidquid figuratur longum secundum modumorgani ante perfectam concordantiam, dicitur esse longum’). This seems to imply that the final note of a clausula can be a breve if the notation suggests it; Garlandia's second rule has been made into a more general principle, in effect restricting the principle of consonance, Garlandia's rule 1, entirely to opening simultaneities. Symptomatically, the St Emmeram Anonymous omits the first rule altogether from his text, undoubtedly through error, as he introduces the first of his remaining two rules with the words, ‘alia insequiturregula’ (ibid., p. 130, 1. 32). Compare Reckow, , Der Musiktraktat des Anonymus 4, ii, pp. 43–4Google Scholar, where it is argued that the anonymous writer deliberately omitted Garlandia's rule of consonance because he considered organum in speciali to be mensural in conception, and therefore not in need of the principle of consonance as Reckow interprets it.

83 Ibid., i, p. 79, ll. 2–5: ’regula est: omnis paenultima ante pausationem, quae dicitur finis punctorum, longa est. Et si paenultima fuerit tonus in duplo supra tenorem ut in organo puro, optime erit concordans, quamvis tonus non sit concordantia.’ The passage goes on to compare the treatment of cadential dissonance ‘inter puros organistas et inter Lumbardos organizantes’, p. 79, 1. 5 – p. 80, 1. 6, the latter perhaps reflecting an earlier style such as that taught by Guido d'Arezzo.

84 Compare the perceptive observation of Theodore Karp that by distinguishing between modus rectus and non rectus ‘Garlandia may have been seeking merely to draw a distinction between the strict confines of the core of modal theory and the liberties allowed in actual modal rhythms’; ‘Towards a Critical Edition of Notre Dame Organa Dupla’, The Musical Quarterly, 52 (1966), p. 358, no. 14Google Scholar. Although I have interpreted the theoretical evidence in a wholly different manner from William Waite, the results of the present study suggest a manner of transcription for sustained-tone organum that is not unlike the one presented in The Rhythm of Twelfth-Century Polyphony in its broad outlines, the major difference involving the treatment of structural points. On a more subjective level. I find many of Waite's readings unnecessarily fussy and ‘baroque’ in character. The notation of modus non rectus is inherently multiform in its rhythmic implications, and the problem of how to preserve this aspect of the musical style in modern transcription has yet to be adequately addressed.

85 Rebecca Baltzer has pointed out the influence of Garlandia's mensural notation on the notation of the organa in Wolfenbüttel 1099; Thirteenth-Century Illuminated Miniatures and the Date of the Florence Manuscript’, Journal of the American Musicological Society, 25 (1972), p. 17Google Scholar (she draws attention to discantus specifically, but these traits are equally evident in organum purum sections, as, for example, on fol. 47r). The mensurally clarified notation in Berlin lat. 4° 523 is more striking still. In this manuscript it is precisely the material in modus non rectus that is notated mensurally, and not the discantus or the sustained-tone writing in modus rectus (which needs such clarification much less). The result is a tendency for the flexible rhythmic designs of the organum in speciali sections to be tightened into a kind of flow approaching that of the strict modal patterns, thereby neutralising the differences between the two kinds of modus. It is by no means clear whether Anonymous iv, writing two generations after Garlandia, intended his seventh chapter to be read in terms of a modally or a mensurally written organum source. His remarks concerning the ‘principle of consonance’ might suggest the former, but other aspects of his discussion — above all, his citation of a phrase of copula that seems to be identical with the redaction of this music in the mensurally written source, Montpellier H.196 (Reckow, , Der Musiktraktat des Anonymus 4, i, p. 84, ll. 14–19)Google Scholar — implies quite the opposite. So also does his long excursus on the development of mensural notation that follows immediately upon his famous account of Leoninus's magnus liber organi and Perotinus's ‘abbreviation’ of it (Ibid., i, p. 46, ll. 5–20). Anonymous iv notes with regard to music in cum littera notation that older generations had had to cope with copies of the repertory in non-mensural notation, and that the greatest part of their understanding of how to perform such modal redactions was communicated through precepts that were not related to any explicit representation in the notation (‘Maxima pars cognitionis antiquorum fuit in praedictis sine materiali significatione’; Ibid., i, p. 50, 11. 5–6), but that the introduction of mensural note-forms had greatlyexpedited the task of learning the music (see the whole passage, Ibid., i, p. 49, 1. 31 – p. 50, 1. 13). He then adds that ‘abbreviatio erat facta per signa materialia a tempore Perotini Magni e parum ante’ (i, p. 50, ll. 14–15), which I take to be a reference to the mensural redaction of the repertory. (On my interpretation of Perotinus's abbreviatio of Leoninus's liber organorum as an ‘edition’ or ‘redaction’, see Roesner, ‘The Problem of Chronology’, pp. 377–9.)
