Does the music genre you play change how you hear the beat?
Musicians trained in different genres placed the beat of the same sounds at different moments, and folk fiddlers tolerated the widest spread of 'on-time' positions.

Study at a glance
- Design
- Cross-sectional — Three-group comparison of expert musicians (folk, jazz, producers) on within-subject click-alignment and tapping tasks with 2x2 Attack x Duration stimuli in three sound categories
- N
- N=59 · 60 musicians recruited; one producer excluded for erratic tapping, leaving 59 analysed (19 folk, 20 jazz, 20 producers)
- Population
- Professional musicians and music producers in Norway specialising in jazz, Scandinavian fiddle music, or computer-based dance/hip-hop production
- Outcome
- Perceived beat location (P-center, ms after onset) and its variability (beat-bin width) in click-alignment and tapping tasks

What they did
The researchers recruited expert jazz musicians, Scandinavian folk fiddlers and electronic-music producers. Each person aligned a click track to a looped sound (a perception task) and tapped clave sticks along with it (a production task). Sounds came from the folk/jazz world (acoustic kick, electric bass, fiddle), the electronic world (808 kick, synth basses), or were neutral noise bursts, each varied in how fast the sound rose (attack) and how long it lasted (duration).
What they found
Slow attacks and long durations pushed the perceived beat later and made it less consistent for everyone. Producers located the beat earliest on average (about 26 ms after onset versus 37 ms for jazz and 40 ms for folk), and folk musicians were the most variable (22 ms versus 15 ms for producers). The biggest group differences came from a single long, slow fiddle sound, where folk and jazz musicians placed the beat late and very inconsistently; even for neutral noise sounds, folk musicians were more variable than producers.
The limits
What it doesn't show
Participants were not randomly assigned to genres, so the groups also differ in age, instrument (folk players were mostly bowers and singers) and possibly other habits; the authors could not separate instrument training from genre training. The strongest effects rest on one stimulus, the long fiddle sound, so the pattern may not generalise to other genre-typical sounds. Groups were tested on different computers and in different settings for the click task, and sound loudness was balanced by ear. The study also cannot say whether listening exposure alone, without performing, would produce the same effects.
Key terms
- P-center
- The moment within a sound that a listener perceives as its beat location, usually somewhere between the acoustic onset and the first energy peak.
- Beat bin
- The range of time positions a listener accepts as 'in time' for a sound, measured here as the variability of click or tap placements.
- Musical enculturation
- The way long-term immersion in a musical culture or genre shapes a person's perception and production of music.
- Attack (rise time)
- How quickly a sound reaches its peak loudness; fast attacks are sharp, slow attacks swell in gradually.
- Sensorimotor synchronization
- Coordinating a movement, such as a tap, in time with an external rhythm.

Common questions
Why would being more familiar with a sound make timing less precise?
In Scandinavian fiddle music flexible, 'breathing' timing is an aesthetic ideal, so experts in that tradition seem to treat a wide window of positions as acceptable. Familiarity brings genre timing norms, not just sharper acuity.
Why include genre-neutral noise sounds?
They carry no stylistic associations, so any group difference on them points to general, low-level timing habits rather than recognising a familiar genre. Folk musicians were still more variable than producers on these sounds.
Why did producers place the beat earlier?
The authors suggest producers listen to the sound itself as audio to be nudged on a screen, whereas performers hear it as the result of a bodily action, such as a bow stroke that 'arrives' after it accelerates.
