Some languages are iambic, others trochaic and others mix properties (or are 'incoherent') of iambic and trochaic patterning. If you can read Spanish Carolina Gonzalez wrote an <a href="https://sedyl.cnrs.fr/amerindia/articles/pdf/A_39_05.pdf">overview</a>, but otherwise, just check out the citations. Some Pano languages seem to have no clear evidence for a metrical system - as far as I have been able to discern, despite some early preliminary <a href="https://sedyl.cnrs.fr/amerindia/articles/pdf/A_39_04.pdf">(mis)analysis</a>, you <a href="https://pubmed.ncbi.nlm.nih.gov/32359331/">don't need</a> to analyze Chacobo as metrical. Once you incorporate independently necessary tone sandhi rules + intonation, it seems that the motivation for a metrical analysis disappears (or as suggested by one of our reviewers, the metrical structure is there but displays no empirical signal, which may or may not have been a joke). <br></div><div class="gmail_default" style="font-family:monospace,monospace;color:#4c1130"><br></div><div class="gmail_default" style="font-family:monospace,monospace;color:#4c1130">As for the direction of change, I don't know. We haven't been very successful in reconstructing much of anything about Pano prosody to my knowledge.
If Chacobo represents the older system, the extant iambic/trochaic might have come from something else.

has clearly shifted from having right-headed (iambic) feet to left-headed
(trochaic) feet or vice versa? I’m studying a language variety where this seems
to be the case. It’s a quantity-sensitive system, so the change mainly affects
strings of light syllables. Any examples or suggested resources would be
helpful, thanks!<span></span></p>
