To begin with, I play an ocarina.
Not many of the songs I am interested in have tabs, so I find music sheets and try to remember everything I learned in the piano class I took some years ago.
Now I think I know most basic symbols (notes, keys, ties, ext) but then I came across a little eighth note above a couple of the regular notes. They weren't connected it was just an eighth note to the left of the note, but I can't find this in my old text book.
The notes themselves are eighth notes, but the little symbol isn't next to all the eighth notes so I feel like its important. I can't really start practicing until I know what it mean, so if anyone has any clue it would be a big help.
