Introduction

As the Latin form of the Greek ὄργανον (organon: “tool,” “instrument,” “systematic principle”), the word organum refers most typically to a specimen of vocal polyphony, especially one that has a preexisting liturgical chant as one of its voices. Examples of works fitting this generic label appear primarily from the 9th century to the 16th century, after which other practices, genres, and styles begin edging it out as a descriptive marker. The initial derivation of the term from the musical instrument (the organ) is unlikely. Rather, the most likely stimulus for its adoption lies in its association with the systematic measurement of musical consonances, particularly the perfect intervals of the fourth, fifth, and octave. Additionally, the term could encompass the specific voice (or voices) added to the chant (itself usually called vox principalis [principal voice], and, later, tenor) as well as the entire musical product. Descriptions of organum arise around the same time as the first examples of notated chants, and these imply an already long-standing practice. The earliest treatments appear embedded in 9th-century theoretical treatises otherwise concerned with teaching principles of Gregorian chant. Here, a few specific rules and precepts could be followed to generate an organum ex tempore that generally lies below the chant. Around 1100, significant changes arise in the appearance of a much greater freedom in the use of harmonic intervals, the placement of the organal voice above the chant, and—later in the century—the option of melismatic elaboration in the added part, creating a new style eventually called organum purum, as distinct from note-against-note discant. Results are visible in the repertories of Aquitanian polyphony and in works preserved in the Codex Calixtinus. By the end of the 12th through the mid-13th centuries, a high point of cultivation is reached in the repertory associated with the Paris cathedral of Notre Dame, with (a) the clarification of rhythm in certain segments of compositions; (b) further stylistic categorization, including a new type, copula, in addition to discant and organum purum; (c) the introduction of the genre of the discant clausula; (d) the preparation of collections of organa encompassing the entire liturgical year; (e) an increase to as many as four parts; and (f) the recognition of the composers Léonin and Pérotin. Later developments in Parisian circles tended to leave organum behind in favor of the motet, while other areas of Europe may demonstrate an engagement with Parisian traditions and/or a reliance on retrospective polyphonic traditions.

General Overviews

With the lack of a book-length overview of organum in all of its manifestations, the articles on “Organum” in the primary music encyclopedias, Reckow, et al. 2011 and Haas 1997, are the best places to start. The bibliographies in these articles are thorough and indispensable as they furnish important items that are not included here. Eggebrecht and Riethmüller 1972–2005 is beneficial for its expansive treatments of terminological issues related to organum. Additional, valuable information is also at hand in related articles in all these publications, such as those on “Discant,” “Clausula,” “Copula,” “Léonin(us),” and “Pérotin(us),” as well as entries dealing with specific musical sources and theoretical writings. The journal articles included here deal specifically with terminological questions. Reckow 1975 goes beyond the author’s own treatment presented in the Handwörterbuch to produce an exhaustive examination of the various connotations of the word organum stretching over more than a millennium; it rejects the initial association of the term with musical instruments. Williams 2001 also tackles the terminological complexities of “organum” and offers a counter to Reckow 1975 in connecting the term with the instrument in specific contexts. The remaining entries connect the user to general collections of primary sources available online. The Digital Image Archive of Medieval Music allows access to high-quality images of a number of medieval manuscripts that contain organum, while the Thesaurus Musicarum Latinarum allows users to view and search the texts of a large collection of Latin music theory treatises based on reliable editions.
