Using tabs means you get the exact information on where to play but not how!
Malotte is nice in his effort to help out with that!
You have the same problem with all tabs. my sons started playing violin last fall and they have rescently started with real notes...
So the best way is to learn the melody and keep taping your feet or something...
The Really good thing is that with tabs it is is to change the key....We just try another harp.
