Relating the evolution of Music-Readiness and Language-Readiness within the context of comparative neuroprimatology
Language- and music-readiness are demonstrated as related within comparative neuroprimatology by elaborating three hypotheses
concerning music-readiness (MR): The (musicological) rhythm-first hypothesis (MR-1), the combinatoriality hypothesis (MR-2),
and the socio-affect-cohesion hypothesis (MR-3). MR-1 states that rhythm precedes evolutionarily melody and tonality. MR-2
states that complex imitation and fractionation within the expanding spiral of the mirror system/complex imitation hypothesis
(MS/CIH) lead to the combinatorial capacities of rhythm necessary for building up a musical lexicon and complex structures;
and rhythm, in connection with repetition and variation, scaffolds both musical form and content. MR-3 states that music’s
main evolutionary function is to self-induce affective states in individuals to cope with distress; rhythm, in particular
isochrony, provides a temporal framework to support movement synchronization, inducing shared affective states in group
members, which in turn enhances group cohesion. This document reviews current behavioural and neurocognitive research relevant
to the comparative neuroprimatology of music-readiness. It further proposes to extend MS/CIH through the evolution of the
relationship of the language- and music-ready brain, by comparing “affective rhythm” and prosody – i.e. by comparatively
approaching the language- and music-emotion link in neuroprimatology.
