“…In actual music, there can be several different possible periodicities to attune to, and meter itself is conceptualized as a nested hierarchy of at least two pulse levels related to each other by simple ratios such as 2:1, 3:1, or 4:1 (e.g., Keller & Burnham, 2005, p. 630;Yeston, 1976). Even if focal attention tasks are used, that is, tasks in which participants are asked to tap at the next higher and/or lower pulse levels (e.g., Drake, Jones, & Baruch, 2000;Drake, Penel, & Bigand, 2000), metric perception as such is only witnessed indirectly. [2] The use of neuroscientific methods has opened new possibilities for the observation of temporal processing, but much work is still needed to clarify how different timing mechanisms (such as "beat-based" and "interval-based" mechanisms; see Repp & Su, 2013, pp.…”
