The Essen Associative Code (EsAC) is probably the oldest, and certainly the longest-surviving, code for music in active use.

Only a small portion of this material is represented in the computer applications described below. The EsAC code is in the field called MEL.  Other fields give the the title, the immediate source, the region from which the song comes, and the general category of the genre (religious, military, etc.). Titles changed over time. Regional information often does not coincide with modern maps. Since 1815 place names and political jurisdictions have changed repeatedly.

The term "EsAC" only properly applies to work developments from 1982 onward. The antecedents of the code can be traced back almost 200 years. No one country or region owns the idea of encoding folksongs, but the typewriter-friendly code that underlies EsAC was in widespread use in various Hapsburg domains in the nineteenth century. Ethnomusicological by Suppan (1966) and others are helpful in tracing the original mandate for folksong transcriptions to the late eighteenth-century Austrian emperor Joseph II, who launched an effort to map the scope of “Hapsburg culture” in all its manifestations.

As the Hapsburg domains expanded in the eighteenth century the diversity of cultural communities became steadily broader. Near the end of the reign of the emperor Joseph II (1765-1790), an initiative to document the practices of these many communities was initiated. Music was one of those practices.

Earlier (1770) [https://de.wikipedia.org/wiki/Johann_Gottfried_Herder Johann Gottfried von Herder] had promoted the concept of the <i>Volkslied</i> (folksong), which was later much romanticized.

Through much of mid-to-late nineteenth century the collection of folksongs was vigorously pursued, not only in Austro-Hungary but in many neighboring states. Much attention was given in the early twentieth century to publication and codification. Inevitably these efforts raised many new questions: (1) Did folksongs with the same title have the same music? (2) Was the same text set to more than one tune? The answers were "Not necessarily" and "Often." With infinite patience the transcription of melodies together with basic information about title, location from which the music came, meter, and so forth was typed. These descriptions of single songs came to fill countless file drawers.

Essen Associative Code

Sample code from the first work in the second EsAC collection of Balladen.

The Essen Associative Code (EsAC) is probably the oldest, and certainly the longest-surviving, code for music in active use. Partly because of its longevity, this code forms the basis of hundreds of thousands of analogue (typescript) encodings in European archives. Only a small portion of this material is represented in the computer applications described below. The EsAC code is in the field called MEL. Other fields give the the title, the immediate source, the region from which the song comes, and the general category of the genre (religious, military, etc.). Titles changed over time. Regional information often does not coincide with modern maps. Since 1815 place names and political jurisdictions have changed repeatedly.

Origins and History to 1982

The term "EsAC" only properly applies to materials encoded from 1982 onward, but the antecedents of the code can be traced back 200 years. The distinction of EsAC was that it was adapted to desktop computers running DOS. No one country or region owns the idea of encoding folksongs, but the typewriter-friendly code that underlies EsAC was in widespread use in various areas of Central and Eastern Europe in the nineteenth century. Ethnomusicological studies by Ivo Suppan (1966) and others locate the original mandate for folksong transcription to the Austrian emperor Joseph II, who launched an effort to map the scope of “Hapsburg culture” in all its manifestations. (The material was transcribed by hand, but scholars have demonstrated that transcriptions were sometimes "regularized" to conform to Austrian models.)

Earlier (1770) Johann Gottfried von Herder had promoted the concept of the Volkslied (folksong), which was later much romanticized. Collections assembled under this more intellectual impetus might consist entirely of text or combine other of music with text, but the emphasis remained on versification, poetic meters, and aesthetic parallels between music and poetic content. In 1811 the Gesellschaft der Musikfreunde appealed for the contribution of songs from all parts of the monarchy.

Motivations for Folksong Analysis

The most potent question that folksong researchers began to ask as they organized this growing body of material was: How does the process of "morphing" (change by slow degrees) occur? Can the pathways of change be predicted? Can styles of adaptation be linked to certain regions? These open-ended questions proved difficult to answer. They continue to be asked today. Stabilizing forces are equally important. Many folksong researchers consider lyrics to be a stabilizing influence on meter and phrase structure, if not directly on pitch or finite elements of rhythm. EsAC builds on this idea by encoding phrase by phrase according to lyrics. Then analysis routines seek to determine whether metric xx. ==

The Work of the Essen Hochschule für Musik

The adaptation of the code was carried out by Helmut Schaffrath, beginning in 1982. The EsAC repertory corresponds in large measure to the German Volkslied dataset used in Wolfram Steinbeck's dissertation, Struktur und Ähnlichkeit. Methoden automatisierter Melodienanalyse (1982), which explored encoded musical content in mainframe programs. The data is separately described in Steinbeck's Die Liederbank Kiel (1976). Schaffrath's personal interest was in the traditional music of Southeast and East Asia.

Teaching at the Hochschule für Musik in Essen (a center for the collection and publication of German folksongs in c. 1900), Schaffrath viewed the advent of the personal computer as an invitation to enable researchers to conduct their work systematically. This required the adaptation of the data to the desktop computers, where, it was hoped, printing and sound output could be generated from the song encodings. He and his students (mainly Barbara Jesser and Ulrike Franzke) created a set of analysis tools for the monophonic code that collectively bore the title MAPPET (Music Analysis Software Package).

Numerous projects based on EsAC, under the auspices of the International Council for Traditional Music, collapsed after Schaffrath's unexpected death in 1994. Data in EsAC has been translated to many other music formats, often for the purpose of testing music software. Schaffrath's data and software, as described here, were transferred to Ewa Dahlig-Turek, now professor of musicology in the University of Poznan (PL).
