Aigen states that "when [a] groove is established among players, the musical whole becomes greater than the sum of its parts, enabling a person [...] to experience something beyond himself which he[/she] cannot create alone (Aigen 2002, p.34)". Jeff Pressing's 2002 article claimed that a "groove or feel" is "a cognitive temporal phenomenon emerging from one or more carefully aligned concurrent rhythmic patterns, characterized by...perception of recurring pulses, and subdivision of structure in such pulses,...perception of a cycle of time, of length 2 or more pulses, enabling identification of cycle locations, and...effectiveness of engaging synchronizing body responses (e.g. dance, foot-tapping)". Neuroscientific perspectives The "groove" has been cited as an example of sensory-motor coupling between neural systems. Sensory-motor coupling is the coupling or integration of the sensory system and motor system. Sensorimotor integration is not a static process. For a given stimulus, there is no one single motor command. "Neural responses at almost every stage of a sensorimotor pathway are modified at short and long timescales by biophysical and synaptic processes, recurrent and feedback connections, and learning, as well as many other internal and external variables". Recent research has shown that at least some styles of modern groove-oriented rock music are characterized by an "aesthetics of exactitude" and the strongest groove stimulation could be observed for drum patterns without microtiming deviations. Use in different genres Jazz In some more traditional styles of jazz, the musicians often use the word "swing" to describe the sense of rhythmic cohesion of a skilled group. However, since the 1950s, musicians from the organ trio and latin jazz subgenres have also used the term "groove". Jazz flute player Herbie Mann talks a lot about "the groove." In the 1950s, Mann "locked into a Brazilian groove in the early '60s, then moved into a funky, soulful groove in the late '60s and early '70s. By the mid-'70s he was making hit disco records, still cooking in a rhythmic groove." He describes his approach to finding the groove as follows: "All you have to do is find the waves that are comfortable to float on top of." Mann argues that the "epitome of a groove record" is "Memphis Underground or Push Push", because the "rhythm section [is] locked all in one perception." Reggae In Jamaican reggae, dancehall, and dub music, the creole term "riddim" is used to describe the rhythm patterns created by the drum pattern or a
