Humans are well-equipped to move along with auditory rhythms via finger or foot tapping, body swaying or walking (Leman et al., 2013; Sowiński and Dalla Bella, 2013). Individual differences in auditory-motor synchronization abilities (AMS) are observed in the general population (Repp, 2010; Sowiński and Dalla Bella, 2013; Palmer et al., 2014), and exacerbated by disorders (e.g., language/speech disorders, Lundetræ and Thomson, 2018; Ladanyi et al., 2020; Parkinson, Yahalom et al., 2004; Puyjarinet et al., 2019). Describing these individual differences can shed light on the cognitive mechanisms underlying the rhythm system in healthy and patient populations (Dalla Bella, 2020; Damm et al., 2020; Ladanyi et al., 2020). Finger tapping to test AMS (Repp, 2005; Repp and Su, 2013) is used in test batteries like the Battery for the Assessment of Auditory Sensorimotor and Timing Abilities (BAASTA, Dalla Bella et al., 2017), and the Harvard Beat Assessment Test (H-BAT, Fujii and Schlaug, 2013). Tapping performance is typically measured in the lab with tapping pads or dedicated sensors, which afford high temporal precision (≤1ms), but make the method quite unsuitable to be used outside the lab.
