Yes. I mean that we must not to repeat or skip notes, for example from D to E we can get a half tone in to ways 'D' -> 'Eb' or 'D' -> 'D#' the valid one for the kata is the first.

Thanks for the feedback :-)

Nice idea.

I waasn't sure exactly when to use which accidental, so I stuck with sharps. However, thisfailed me. Also, it would be helpful for you to explain the "notes notation sequence."

Thanks a lot.
