Is 4/4 the rhythm of our biology? (Fiveash et al., 2023)

Fiveash et al., 2023, authored Can rhythm-mediated reward boost learning, memory, and social connection? Perspectives for future research - ScienceDirect states:

One of the most prominent interactions between the listener and external rhythmic information occurs via synchronization/entrainment (we will not go into this distinction here, but see Obleser and Kayser, 2019 for discussion of the differences in terminology, and note that we are discussing entrainment in the broad sense). This process can be conceptualized as the coupling of internal oscillations (or other forms of endogenous timekeeper mechanism) with the periodicity perceived in the external rhythm, such as the musical beat or meter. Rhythmic entrainment is pervasive, and can be observed at physiological, behavioral, and neural levels (Fujioka et al., 2012; Large, 2008; Trost and Vuilleumier, 2013). At the physiological level, beat regularity can, via different tempi, modulate cardiovascular and respiratory patterns (e.g., Khalfa et al., 2008), and even pupillary responses (Fink et al., 2018; Marimon et al., 2022). At the behavioral level, entrainment is apparent from listeners being able to perceive a musical beat, benefit from events occurring on the beat (e.g., faster processing), and also move their body in time with this beat (Damm et al., 2020; Nozaradan et al., 2015).

I think there is significant link between the lub-dub of the heart and common time. You might say 2/2, cut time, corresponds better with the lub-dub of the heartN
