Letters as note heads

[Kyle Wightman Baldwin]

I'm trying to create a handout where the note heads are actually letters.  

I'm sure I'm not the first one to do this, but I'm having a hard time finding it.  I came across the "Easy play" note heads, but they are too small and I would prefer it without the actual note heads. 

An example of what I'm trying to accomplish is below.

Thanks!
