Ok, thanks!
BTW, I think that in that snippet some pitches are not correct.
I'll write to lilypond-bug.

I'll send a bug report.

Now I understand how harmonicsBy... work.
I have a couple of questions (see file attached):

* \harmonic prints 19th fret instead of 7th and 24th fret instead of 5th
on TabStaff.  I don't think it's desirable, because it's more likely
that 5th and 7th frets will be used.  I wonder if \harmonicByFret was
introduced to solve this problem.

* as you can see in the example, when \harmonicByFret and
\harmonicByRatio are used, string numbers don't show up in Staff (they
do if \harmonic is used).

Cheers,
Federico
