Thank you for your input.
I noticed that shift sign in the Code Book, but it is labeled "a straight line between two noteheads". That is not what I have. I have a minus sign in the fingering. It is used for the first finger placement after a shift (to a new position). So that would be, in braille, position sign, octave sign, note, fingering. If I used the (4, 1), where would it go? My inclination is to put in a general TN and leave it out. Also, sometimes the fingering number is the same as the previous note, and sometimes it is not. The author only uses this in the demonstration exerciss, not in the actual songs. I think it is a visual, and would make clutter.
What do you think?
