The editors of this volume ask whether the approaches of ethnomusicology and historical musicology to investigating musical performance can be brought together. In order to answer that question and assess future prospects, it is necessary to look in more detail at the approaches taken within the two disciplines and their historical trajectories. The aim of the present chapter is to make such a comparison, addressing in particular the place of âempiricalâ methodologies (intended as those involving the analysis of quantitative performance data describing for instance timing, pitch, loudness or movement) in both disciplines.
For some researchers in both ethnomusicology and historical musicology, the empirical investigation of performance has long been an essential element of the serious study of music. For others, such investigations have been at best an optional extra, if not actively resisted, an attitude associated with a conception of each discipline as exclusively humanistic. While the trajectories of empirical methodologies in the two disciplines have much in common, interactions between them have been rare. Eric Clarkeâs 2004 overview of empirical research in historical musicology, for example, makes no reference to research on non-Western music, nor does Caroline Palmerâs chapter on music performance in Diana Deutschâs The Psychology of Music (Palmer 2013). Although Alf Gabrielssonâs extensive account in an earlier edition of the same work (1999) mentions ethnomusicologist John Bailyâs work on motor patterns in instrumental performance (e.g. 1985), and Jane Davidson (2009) adds to this an acknowledgement of the seminal work of John Blacking (1977), it is hard not to conclude that ethnomusicology has been of marginal interest to music psychology, while empirical approaches in historical musicology have tended to align with this pattern. A similar charge could perhaps be levelled in reverse at ethnomusicologists such as Charles Keil, who developed his own distinctive theory of performance timing with little reference to the history of psychological research on the topic (1987, 1995). The general rule seems to have been that historical musicology and ethnomusicology have behaved as if the other did not exist.
The next two sections outline brief histories of empirical methods in historical musicology and ethnomusicology, respectively; in both cases I go into more detail on a selection of sources relating to rhythm and timing, which help to highlight some of the reasons for the disciplinary divergence. This is also a particularly promising area of current and future cooperation, as the work on entrainment by this author and colleagues may demonstrate (Clayton et al. 2005). The last section briefly addresses some of the critiques that have been levelled against these methods within the two music disciplines, before discussing some common ground and arguing that a degree of convergence in recent years raises the possibility, albeit not the certainty, of a future marked by productive interdisciplinary convergence.
Trajectories: Musicology, psychology and performance
Recent histories of empirical musicology cite a seminal study carried out in the Sorbonneâs experimental psychology laboratory by Alfred Binet and J. Courtier (1895), in which the authors describe a mechanical apparatus for recording the keypresses of a pianist. Their primary interest was movement control â the same authors had published a paper two years earlier analysing upper-limb movement in drawing (Binet and Courtier 1893) â and their focus was on the regularity of force and timing under specific biomechanical constraints, rather than the contribution of this control to musical expression. Building on this and a handful of other studies of timing â some using a âtappingâ paradigm that continues to be applied to this day â the American psychologist Charles H. Sears attempted detailed studies of musical performance for the first time in 1902. For this investigation, a reed organ rather than a piano was used, with timing information collected by means of electrical contacts attached to the underside of the keys, the signal from the highest (soprano) part being traced on a kymograph drum (see Brock-Nannestad 2014 for a description of this technology). Four musicians were asked to play a selection of hymns on the organ, and Sears calculated the differences between individual interpretations, including their overall tempo and regularity. As Sears put it, âHow far the trained musician accomplishes what the notes set before him indicate and what he sets out to do is an interesting question not only to the psychologist, but also to the musicianâ (1902: 28). Thus, while the inspiration was psychological, for the first time the implications of such empirical work for musical practice and pedagogy began to be considered.
The next major landmark is surely provided by the body of work conducted by Carl Seashore and colleagues. Seashoreâs 1919 monograph The Psychology of Musical Talent focuses on perceptual and productive capacities, developing methods of measuring musical talent and thus assisting pedagogy. He writes of his aim that âit may serve as a somewhat intensive presentation of a specific subject for the student of educational psychology, child-study, vocational and industrial selection, or vocational and avocational guidanceâ (1919: vii). Over the 1920s and 1930s, however, his attentions turned more to the measurement of expert musical performance, striving alongside his original aims to empirically identify the qualities of Western art music well performed. His University of Iowa laboratory, then, had a more musicological focus than most of its precursors.
The later work is conveniently collected in Seashoreâs 1938 volume Psychology of Music. Among many other topics can be found those based on audio recordings (for example, investigating vibrato), and studies of piano playing using the âIowa piano cameraâ, another in what has proved a long line of devices for capturing keyboard performance (1967 [1938]: 233ff). Indeed, he begins his introduction to the 1936 collection Objective Analysis of Musical Performance by enthusiastically acknowledging the impact on academic research of technological advances in sound and film recording, telephony, and broadcasting (1936: 5). Sound recording had been enthusiastically adopted by music researchers ever since J. Walter Fewkes made the first âfield recordingâ on wax cylinder in 1890, soon after Thomas Edisonâs invention became commercially available in 1888. While comparative musicology settled on manual transcription from sound recordings as its core method, psychologists experimented with methods of automatic graphical representation â approaches that only occasionally impacted on musicological research.
Despite the fact that motor control had been a concern of psychologists studying music performance from Binet and Courtier onwards, little work was done on bodily movement â and technology may have been a factor here in a more negative sense. Doing so from film would have been an even greater challenge than working from sound recordings or from the kind of data produced by piano recording devices. In Seashoreâs chapter on âPrimitive musicâ he nonetheless expresses great enthusiasm for the potential of sound film as a research tool (1967 [1938]: 346). His material for this chapter is all derived from comparative musicologist Milton Metfesselâs 1928 study of âNegro songsâ, which makes extensive use of photography, but as a way of recording aspects of the auditory signal, not bodily movement (so-called âphonophotographyâ).
Until this point there had been little acknowledgement of comparative musicology in studies of Western music performance. In Seashoreâs introduction to Metfesselâs volume, though, he notes the history of investigating âprimitive musicâ from sound recordings, suggesting that new techniques now allowed for the photographic recording of sound (1928: 7, credited to a paper first read in 1924). He closes his introduction with a familiar plea to study and preserve ânativeâ songs from around the world before these diverse styles were âobliteratedâ by culture contact (1928: 16). Metfesselâs study puts Seashoreâs proposal into practice through a series of meticulous analyses. It is nonetheless striking that eight years later, all Seashore could muster for his Psychology of Music collection was a summary of the same findings â in practice they had not served as the inspiration to others that he had apparently hoped.
Little progress seems to have been made in the four decades following Seashoreâs 1938 book, until Dirk-Jan Povelâs 1977 study of rhythm in the performance of a section of Bachâs Well-tempered Clavier. This study introduces an apparently new methodology, namely the extraction of event onset times from audio recordings â a complicated procedure at that time, involving the filtering of tape recordings of harpsichord performance. Four years later, L. Henry Shafferâs study introduced photovoltaic cells to a grand piano, an update of Seashoreâs approach, but now storing and manipulating the data on a computer. It is worth noting that Shafferâs study goes into significant detail on theories of motor control, once again the main area of psychological interest (1981). The same apparatus is referred to in Eric Clarkeâs 1985 study of the performances of Eric Satieâs piano music, but by 1990 Clarke and Carol Krumhansl were reporting the use of MIDI to record timing directly to the computer. One thing that has remained consistent since 1895 has been the prominent place given to the study of keyboard performance: in his 2004 overview, in fact, Clarke focuses almost exclusively on this topic. The nature of the instrument and the technologies available for extracting data means that rather than pitch â which appeared to be of great interest to Seashore â studies have since focused increasingly on timing, and to a lesser extent on dynamic contours. This is not to say that the empirical study of Western art music has actually focused exclusively on keyboard performance since the 1970s â witness for example studies of movement and gesture in singers and instrumental soloists (e.g. Davidson 1993; Wanderley et al. 2005). Nonetheless, Clarke will have had little concern over his characterisation of the field.
Such has been the explosion of empirical study of musical performance since the 1980s that it is not possible to give a comprehensive overview here. Rather, it will be more productive to consider the role and the extent to which these âempiricalâ methods have been integrated into the mainstream of historical musicology. Particular mention should be made here of the CHARM1 and CMCPC2 projects which brought together some of the United Kingdomâs most distinguished musicologists: Eric Clarke (a pioneer in the application of empirical methodologies and psychological perspectives, already cited), Nicholas Cook, John Rink, Daniel Leech-Wilkinson and others. These projects should be considered also in the context of another scholarly trajectory that owes its existence to technology: the qualitative and interpretive study of historical sound recordings, as pioneered by Robert Philip (1992, 2004). The CHARM initiative, in a sense, brought together the qualitative historical approach of Philip with the quantitative and psychologically informed approach of Clarke, with the aim of establishing a more secure empirical basis for musicology. As Cook and Clarke explain in the introduction to their Empirical Musicology volume:
Empirical musicology ⌠can be thought of as musicology that embodies a principled awareness of both the potential to engage with large bodies of relevant data, and the appropriate methods for achieving this; adopting this term draws attention to the potential of a range of empirical approaches to music that is, as yet, not widely disseminated within the discipline.
(2004: 5)
Whether one agrees with Cook and Clarke that where data is available and hypotheses can be tested, musicologists should be willing to do so, or whether one is invested in the idea of musicology as an exclusively humanistic discipline that avoids quantitative data, CHARM and its successor surely achieved the objective of drawing attention to empirical methods. One of the achievements of this project was to establish the method of analysing sound recordings within the mainstream of musicology, either to compare multiple performances of the same work (Cook 2007) or to explore some of the finer details of individual musiciansâ styles. In the latter case, Leech-Wilkinson manages to incorporate aspects of empirical analysis in support of a fundamentally humanistic, musicological argument, albeit framed in his Preface as the outcome of empirical analysis: âNothing comes across more clearly from this work in musical science than that the performer is the source of all the most specific musical meaningâ (2009).
It is equally true that many musicologists have simply ignored the application of such approaches. As Georgina Born writes, this work offers a radical challenge to prevailing modes of musicological discourse:
While [CHARM] is a welcome development, it indicates the profound dislocation that has existed between the philological orientation of score-based musicology and the aural-oral nature of recording ⌠the terms of the detente remain uncertain: cognitivist and positivistic, or hermeneutic and cultural-theoretical?
(Born 2010: 235â6)
Whether the term âpositivisticâ is a fair description of CHARM is a question worth considering at more length than is possible here, but the point is that it has sometimes been perceived as such. Empirical methods cannot simply be regarded as add-ons, but rather profoundly challenge aspects of prevailing musicological p...
