Tiers for nasality make definitely sense in the tukano data: just assign for every sound in a word, whether it is a sound occuring in a word that begins or contains a nasal. We can even make different kinds of nasal tiers:
full nasal (nasal anywhere in the word, broadest tier)
initial nasal (nasal in initial), or
syllable-onset nasal
One can expand this ad libititum, and adapt it on a family-specific basis. For Chiense dialects, for example, we would want to assign nasality based on the offset, etc.
