That's interesting Carol. I agree that rhythm is an important part of 'languaging'. Also I think that ethnic groups {if not races} have sound preferences that IMO are much more 'nuture' and have very little if anything to do with 'nature'.

With African Americans these sound preferences are reflected in the popularity of certain personal names. The 'sha' {or 'cha'} sound {"Shante'"; "Shadaya"; "Shakira" are very 'hot' now for females {and have been for at least 20 years}. For males the "aun" sound is very popular. Some examples are names with the'juan' sound {which is pronounced two ways-"WAHN" or "JEW-wahn"} or "von" {vahn} or "shawn" {"shaun"; "shon"; "sean"} names or suffix {such as Dashon which is pronounced 'day-shawn' and whose nickname is "Day Day"}...

Singers whose voices are gritty or rough is another example of sound preferences among not just African Americans but I believe other persons from the African Diaspora...

I could ramble on but my rambling time is up.

Peace!
