  The TIME project: Timing and Sound in Musical Microrhythm (2017–2022) studied microrhythm; that is, how dynamic envelope, timbre, and center frequency, as well as the microtiming of a variety of sounds, affect their perceived rhythmic properties. The project involved theoretical work regarding the basic aspects of microrhythm; experimental studies of microrhythm perception, exploring both stimulus features and the participants’ enculturated expertise; observational studies of how musicians produce particular microrhythms; and ethnographic studies of musicians’ descriptions of microrhythm. Collectively, we show that: (a) altering the microstructure of a sound (“what” the sound is) changes its perceived temporal location (“when” it occurs), (b) there are systematic effects of core acoustic factors (duration, attack) on microrhythmic perception, (c) microrhythmic features in longer and more complex sounds can give rise to different perceptions of the same sound, and (d) musicians are highly aware of microrhythms and have developed vocabularies for describing them. In addition, our results shed light on conflicting results regarding the effect of microtiming on the “grooviness” of a rhythm. Our use of multiple, interdisciplinary methodologies enabled us to uncover the complexity of microrhythm perception and production in both laboratory and real-world musical contexts.

  Recent research has shown that the shape, timbre, and intensity of a sound influence the perception of its timing at the micro level of rhythm. In this case study of contemporary Norwegian jazz, we investigate to what extent jazz musicians intentionally use sonic features to shape the micro level of rhythm in their performances. First, we provide an overview of existing research into microrhythm in jazz and auditory perception studies. Then we present results from interviews with five expert jazz musicians about how playing techniques and sound qualities of specific instruments are utilized to influence the perception of timing. We also analyze two selected performances by the musicians to explore the effects of interaction between sonic features and timing in a musical context. The article concludes by discussing the results in the context of findings from empirical research into microlevel auditory perception regarding the perceptual center of sounds (P-center) and auditory stream segregation. The study demonstrates the need to move related research beyond the temporal domain, and to cultivate a more holistic approach to what constitutes groove in jazz and related genres.

  Musical expertise improves the precision of timing perception and performance – but is this expertise generic, or is it tied to the specific style(s) and genre(s) of one’s musical training? We asked expert musicians from three musical genres (folk, jazz, and EDM/hip-hop) to align click tracks and tap in synchrony with genre-specific and genre-neutral sound stimuli to determine the perceptual center (“P-center”) and variability (“beat bin”) for each group of experts. We had three stimulus categories – Organic, Electronic, and Neutral sounds – each of which had a 2 Å~ 2 design of the acoustic factors Attack (fast/slow) and Duration (short/long). We found significant effects of Genre expertise, and a significant interaction for both P-center and P-center variability: folk and jazz musicians synchronize to sounds typical of folk and jazz in a different manner than the EDM/hip-hop producers. The results show that expertise in a specific musical genre affects our low-level perceptions of sounds as well as their affordance(s) for joint action/synchronization. The study provides new insights into the effects of active long-term musical enculturation and skill acquisition on basic sensorimotor synchronization and timing perception, shedding light on the important question of how nature and nurture intersect in the development of our perceptual systems.

  In his dissertation, Eirik Jacobsen is concerned with the encounter between independent music culture and social media technology. The thesis focuses on the distributional and relational labor involved in carrying out musical projects and explores how independent artists and bands make use and sense of social media technology. This involves a theoretical and empirical investigation of how indie artists form and maintain relations in their socioeconomic networks, as well as the significance of social media for shaping and expressing social identities. The study employs an ethnographic and qualitative approach, involving interviews with local indie performers in Oslo, Norway, as well as critical content analyses of social media material. The study is situated in the fields of popular music and media studies and seeks to understand in what ways technological developments within social media have been crucial for local indie musicians in the context of the contemporary music industry, as well as what it signifies for local indie music as a sociocultural concept.
