title_body: Adding entire musical concepts to expand vocabulary I want my language, Syn, to be as precise, efficient, unambiguous, and aesthetic as humanely possible. To do that, I think even the texture, dynamics, rhythm, and the likes should be accounted for.
  
  As far as I know, only Mandarin incorporates changes in intonation corresponding with a different meaning of the same spoken word, but even that can be hard to notice for non-speakers.
  
  
  
  Are there any other languages that incorporte musical concepts?
  
  If there are, how did people manage to use those concepts?
  
  If there are none yet, will such a language possess an added difficulty when speaking it?
  
  
  
  I imagine that the native speakers of Syn would be naturally adept in tone recognition, and every conversation would seem like an a capella get-together.
upvoted_answer: There is a precedent for the use of a musical tone scale in constructed languages: Solresol, a philosophical language constructed in the 19th century. Some natural languages also have a whistled mode, most notably El Silbo and Pirahã.
  
  I am not aware of a language—neither natural nor constructed—that incorporates the concept of rhythm or other musical concepts.
