Betreft: Consonant Harmony?

>>> nicole perrin <nicole.eap@...> 02/16 2:49  >>>
I was toying with the idea of vowel harmony in a new lang, but I never
really liked it as a trait, so I got curious.  Are there any natlangs
that use "consonant harmony?"  For example, in a particular word, all
the consonants must be voiced?  Or labial?  Or fricatives?  I don't know
which distinction I would choose (voicing, POA, quality, etc.), but do
natlangs do this at all?

I know of Guaraní that consonants may get nasal, depending on the
vowel that has stress. If the stressed vowel is nasal, all preceding
consonants get nasal too.

In my lang Gbwia all consonants in a word get ejective (or implosive
in case of voiced consonants) if the word is in the oblique case.

I think you can choose anything you like (POA, voicing) or even
a combination? Or something like: if there is a bilabial in a word,
all consonants get labialized.
Sounds fun, consonant harmony!
