and indeed if you consider a concrete example of a musical note played by an instrument, what occurs just prior to the phase transition into a musical note?
Well, a lot of that is actually due to insufficient information I think;
We may not be recording the noises made prior to the instrument playing the note; the movement of the fingers on the strings or keys, the air currents. We might have to go back into the neural activity as the rehearsed pattern starts to engage the motor systems but through a gatekeeper that can stop or change it and then you need the gatekeeper’s patterns, and so on… and so i think what you get is a change in type that precedes a change in phrase
