I learned how to input barred numbers (sharps) on the iReal b forum, from dflat who suggested an iPhone app to input unicode diacriticals. I incorporated this into my Rousseau MusicPad iPhone app.

As for the numbering, this tune has a tonal center of Ab = 1, the minor scale starting on 6 (unless you want it in dorian in which case you could use 2). It might seem hard at first but it's actually pretty easy to get the hang of!
