And what would you expect MSPro to do with a .doc file?

um.....display it, same as a pdf?

I assume you are a banjo player, and you can read and play the simple chord charts like you showed us.

Now I give you a violin, and the score of a violin concierto by Paganini. I expect you to play it, same as you do with the chords chart on the banjo.

Some things are not as trivial as you may think.

Your assumption is correct, though I do learn from tabulature also (attached) 

I do understand the difference between a score and a chord chart.  Just not a .doc and .pdf

If I could hear the violin concerto first, I might not need the score in order to play it!   (that is, if I played the violin)
 
My inexperience here, is in understanding how files are structured and how computer programs work.   

I would rather spend the time playing music (and getting my music on the tablet!) than learning about computers.  
But that's why you guys are here, right?  
Thanks for the help.
