title_body: Are there nasalized nasal consonants? As in, [ñ] or [ñ̃]. It seems to me you can make a nasal sound more nasal, maybe by stressing your nose muscles or something in that sense. Does this exist?
  
  EDIT:
  Apologies, I was thinking about Nareal consonants, which do apparently exist. (see answer by me below, the other answers are also good.)
upvoted_answer: Nasal consonants are not nasal because you use any "nose muscles", but because the nasal passage is open and air is passing through it as well as the mouth. To my knowledge, the nasal passage does not have different degrees of being open or closed, so there wouldn't be any way to make a nasal consonant more nasal.
  
  However, there are definitely some sounds that are less nasal than standard nasal stops. Prenasalized and poststopped consonants, where a nasal followed by a non-nasal stop is treated as a single consonant, exist and are phonemic in some languages. There are also denasal phones, in which the nasal passage is open and used as a resonant cavity but air does not flow out the nose (think of how someone sounds when they have a stuffy nose). While denasals are not phonemic in any natlang to my knowledge, they are sometimes allophonic or phonetically present in a language that is losing its nasals.
