[Harp-L] Harmonica for Dummies - anything simpler?

[PMichael Rodgers <pmiker@xxxxxxxxxx>]

I have the Harmonica for Dummies book (and others).  I have been stuck 
in Ch. 3 (music theory) for some time.  Am I really expected to be able 
to play the examples before proceeding to chapter 4?  I know about 
halfs, quarters and eighth notes and such.  I can tell that one note is 
higher/lower than the next and if I think about it, I can name the note 
on sheet music.  Not great but enough to follow along in a hymnal.  But 
the examples!  arrrrrgh.  They are killing me.  If I just listen and 
move on, will I suffer in later chapters?
