Computational role of beta oscillations in beat tracking

Establish whether beta-band oscillations play a computational role in beat tracking in music perception or whether observed beta dynamics are driven by low-frequency auditory–motor coupling mechanisms.

Background

Low-frequency neural tracking supports alignment to musical rhythms, while beta activity in motor regions has been linked to beat and metrical structure. Competing computational models suggest beat extraction via low-frequency oscillator arrays without requiring beta involvement.

Causal tests are needed to determine whether beta contributes computationally to beat tracking or is a downstream consequence of auditory–motor coupling.

References

As such, whether beta plays a computational role in beat tracking or is instead driven by the low-frequency coupling remains an open question.
