It's well established that children from an EXTREMELY early age absorb the sounds of the language they hear, and in later life have an extremely difficult time with sounds in foreign languages that weren't "built in" in infancy and early childhood. Thus, babies and young children raised exclusively with Chinese-speakers are likely to have a difficult time with the "L" sound. Born and raised German-speakers are likely to have trouble with "th", and tend to make is "S" or "T" or "Z".

Seems to me that music is likely to operate by similar rules: The infant/young child brought up on music will relate to those sounds better when older.
