 Kirkpatrick's is the one that opens 
> with a rising fourth (c-f-f-g-a-f-f), while Murray's first line is 
a 
> descending scale(c-c-b flat-a-a-g-f-f-e-d-c).  

I love Away in a Manger, but what does all that alphabet stuff mean?  
I mean, I know it's the notes and everything, but I am musically 
retarded and don't understand!  Could someone explain it to me?

artistic!
