2. The idea of co-instantiaton is also an interesting one:
My gloss for coupling, defined by Martin et al. (2013, p. 469) as ‘the co-selection of linguistic resources across ranks, metafunctions, strata, and modalities which are not specified by system/structure cycles’.
Systems at each stratum make distinct contributions…eg variations in tone and mood couple to instantiate variations in speech function

[1] To be clear, Martin's definition of 'coupling' is invalid, because system/structure cycles do not specify any co-selection of paradigmatic features ("linguistic resources"). To explain:-
The process of instantiation is the selection of paradigmatic features and the activation of realisation statements which specify how systemic options are realised along the syntagmatic axis, whether structural or cohesive. System/structure cycles are the iteration of this realisation relation between axes during logogenesis, the unfolding of text. On this basis, system/structure cycles do not specify which features are (co-)selected; feature (co-)selection is the paradigmatic dimension of system/structure cycles.
[2] To be clear, this confuses instantiation with realisation. Instantiations of "variations in speech function" are the speech function features that are selected during logogenesis. The relation between speech function and mood, and between mood and tone, is realisation, since these three systems are located on three different strata: semantics, lexicogrammar and phonology.
However, strictly speaking, the system of TONE does not realise the system of MOOD, but the system of KEY, which is associated with the system of MOOD (Halliday & Matthiessen 2014: 168). It is the combination of KEY and MOOD that realises SPEECH FUNCTION.
