Recently I've started practicing on my site reading. I don't really find anything online that isn't classical and occasionally, on the musical scores, I come across numbers above the notes. I've seen numbers like "2" or 4" and I've generally assumed that it stands for the finger you're supposed to use to press down on the fredboard to make the note.
But then I stared coming across numbers with an added negative sign such as "-2" or "-4"
I'm not too sure what this means. Could someone shed some light on this for me?
Maybe it has something to do with the position on the fret board your supposed to play the note (I.E. playing a note in second position rather then first). But this doesn't really make any sense to me, it wouldn't need a minus symbol to notate that. Would it?
