I'm not confident I understand how you'd like the letters to align. If you
want the bottom-most point of the letters to touch the staff line (even
though this means that they won't line up as in the text I'm typing now),
then the stencil override Carl mentions might be achieved like this:
\new TabStaff
\with
{
tablatureFormat = #fret-letter-tablature-format
\override TabNoteHead #'whiteout = ##f
}
{
\override TabNoteHead #'stencil = #(lambda (grob)
(ly:stencil-translate-axis
(ly:stencil-aligned-to (tab-note-head::print grob) Y -1)
(ly:staff-symbol-line-thickness grob) Y))
e' f' fis' g' gis' a' ais' b' c'' cis'' d'' dis'' e'' f'' fis'' g'' gis''
}
For some reason, the override won't work for me inside the \with block.
Do you want some separation between the characters and the staff line? If
not, the line-thickness of the staff line should be halved.
HTH,
David
