In ear tests, one is usually required to identify intervals which are played ascending. The first time I had to start identifying them descending, my teacher at the time said, minor 3rds are the easiest to hear, because you hear it all the time in playgrounds when children call out, "Muuuuum - my", in their sing-song voices.
A few years ago, I was sent on a writing course, and the instructor spoke about punctuation marks, and it was actually quite musical the way she talked about it. Unlike in school, where we get taught the rules of when to use each punctuation mark, she spoke about reading aloud and how punctuation marks are instructions for the way a voice is used - e.g. comma is a pause, semicolon is a longer pause, full-stop even longer, question mark is a pause as well as voice rising in pitch, exclamation mark also indicates change in pitch in voice, etc etc
I don't see any difference between language and music - to me, I learn them both in the same way.
