I'd rather prefer, if one could set
stringOneTopmost = ##f
in FretBoards and let the printing-procedure respect it (similiar to TabStaff)

I tried the coding below doing so, but I'm not very happy, it's sort
of "all or nothing"...
\include "predefined-guitar-fretboards.ly"
#(let ((default-fret-table-ls (hash-table->alist default-fret-table)))
(for-each
(lambda (chord-def)
(hash-set!
default-fret-table
(car chord-def)
(map
(lambda (x)
(cons*
(car x)
(- 7 (second x))
(cddr x)))
(cdr chord-def))))
default-fret-table-ls))
melody = \chordmode {
c,
}
\score {
<<
\context ChordNames \melody
\context FretBoards
\with {
highStringOne = ##f
stringOneTopmost = ##f
}
\melody
\context TabStaff
\with {
stringOneTopmost = ##f
}
\melody
>>
}
Cheers,
Harm
