More thoughts.. I like the portamento symbol for the end of the book, where they are only using the numbers, dashes, and carets.
However, we have not fully addressed my question about the fingering with the minus sign, at the beginning of the book. The .pdf I sent is the one that is upside down (sorry). Do you recommend skipping the minus (dash) signs? What about the footnote that the author includes?
I will hold this volume until I hear from you on this issue.
