Choose your own adventure: Vocal jazz improvisation, conceptual metaphor, and cognitive embodiment

Creativity in the form of musical improvisation has received growing attention from researchers informed by the literature on embodiment. To date, this research has focused on the embodied experiences of improvising instrumentalists rather than those of improvising singers. This article investigates the experience of embodiment during improvisation through a systematic analysis of the metaphorical language used by an artist-level jazz singer in her reflections on practice. Extensive interview data with the participant were analyzed to identify and reconstruct metaphorical expressions into conceptual metaphors. In this process, the metaphor of IMPROVISATION IS AN ADVENTURE was identified as the overarching conceptual structure that the participant used to make sense of her experiences of improvisation. This metaphor and its mappings illuminate the cognitively embodied dimension of vocal jazz improvisation. These findings will be of interest to jazz singers and vocal jazz educators who are encouraged to explore more fully the role of the body–mind’s interactions with its environment in order to establish expertise in improvisational ways of knowing. This research illuminates the multidimensional nature of an expert singer’s experiences of improvisation and is presented as a provocation for future research to include singers as participants when investigating musical improvisation and cognitive embodiment.

Interval patterns are dependent on metrical position in jazz solos

During jazz improvisation, performers employ short recurrent musical motifs called licks. Past research has focused on the pitch, intervallic, and rhythmic characteristics of licks, but less attention has been paid to whether they tend to start in the same place within the measure ( metrical dependence). Licks might be metrically dependent, and where a given lick starts in a measure ( metrical position) may thus be part of the performer’s mental representation of that lick. Here we report the use of a corpus study to investigate whether licks are metrically dependent. We analyzed a subset of solos, all those in 4/4 time ( n = 435), from the Weimar Jazz Database (WJD; Pfleiderer et al., 2017). Using a sliding window technique, we identified melodic sequences ( interval n-grams) between 3 and 10 intervals in length. We counted the number of times each interval n-gram occurred, and noted the metrical position of the initial note of each occurrence, using different levels of quantization (8th and 16th note). We compared the entropy of the distribution of metrical positions for each n-gram—with lower values indicating a stronger metrical dependence—against simulated counterparts that assumed no relationship between an n-gram and its metrical position (no metrical dependence). Overall, we found that shorter n-grams were metrically dependent, with varying results for longer n-grams. We suggest two possible explanations: either mental representations of licks may encode their metrical features or the metrical position may make certain licks more accessible to the performer. On the basis of our findings we discuss future studies that could employ our methods.

Mind wandering and musical creativity in jazz improvisation

Mind wandering is a prevalent and ubiquitous phenomenon. Several studies suggest that mind wandering benefits creativity if it occurs in the incubation period of a creative problem-solving task. However, it could be impairing real-time expression of creative behavior if it occurs during the course of a creative task. This dissociation between incubation and performance suggests that mind wandering poses a double-edged sword to creative cognition. Jazz improvisation provides an ecologically useful framework for studying the effects of mind wandering on creativity. Here we hypothesized that mind wandering during a musical improvisation task would be associated with higher levels of musical creativity, compared with on-task attention. Nine experienced musicians performed several jazz improvisation tasks interleaved with the presentation of random thought probes. The results showed that musical improvisation during unintentional mind wandering was associated with higher musical creativity when compared with improvisation during on-task attention. However, mind wandering did not impact overall improvisational quality. Altogether, these data suggest that the positive relationship between mind wandering and creativity also extends to artistic performance domains.

Aebersold’s Mediated Play-A-Long Pedagogy and the Invention of the Beginning Jazz Improvisation Student

In this historical study, I present the emergence and evolution of Jamey Aebersold’s Play-A-Long volumes and their key role in bringing jazz improvisation to formal music education. Drawing on oral histories and using a framework from sound studies, I present chord-scales and pattern playing as Deweyan conceptual technologies that assist beginners in developing a mature technique. I recount how Aebersold learned these as a student of David Baker at Indiana University, then applied the idea through teaching improvisation with the Dorian mode over Davis’s “So What.” In 1967 Aebersold published volume 1, and the Play-A-Long evolved into a system over a dozen years as subsequent volumes included new scale types, like the blues scale; added idiomatic patterns; incorporated his new Scale Syllabus; and licensed standard repertoire. I then describe how these technologies imply the “soloist as such”: a generic model of learning improvisation as a process of learning tunes and tasks from simple to complex around a core unity of theory and performance. This model in particular addressed beginning improvisation and the slogan “Anyone Can Improvise.” Finally, I consider criticisms of the model, note that the chord-scale approach is Black music theory, and suggest future research.

Mixing it Up

Mozart’s musical dice game is one example of how musicians and other artists have incorporated aleatoric elements into their work. Jazz improvisation means every performance is different. Cage left space for the environment to make its own music, but Xenakis took a mathematician’s understanding of randomness and created avant-garde compositions that use the orchestra in new ways. Generative techniques use random numbers to provide new music and other kinds of art on demand. Blocked creativity can be freed by deliberate injections of spontaneity.

Coherence and Musical Meaning in Jazz Improvisation

In the context of improvised music, and more specifically in jazz—a situation in which at least part of the musical “work” is created at the moment it is perceived—the performers find themselves in an ambivalent condition: like their listeners at the same time they perform the music they experience it for the first time. Improvisers experience the musical content they produce in the act of improvisation as an improvised part of a “work”—an update of it. The “work”, in this case, reveals itself at the moment of performance. In this work I discuss the understanding of musical coherence in order to
