You can't because {a b c' d' "1x2x" "x3x4" } is not valid input

Sure, sure! It was just a mistake!! Of course I didn't intend to put the strings inside the brackets.
You could try for
\myFin {a b c' d'} "1x2x" "x3x4"
exactly :)
instead which is obviously done using
myFin = #(define-music-function (m a b) (ly:music? string? string?)
#{ \addStringNumber \addFingering $m #a #b #}
)
Yes it is obvious also for me. But beside the previous error I probably forgot two or three others insignificant details :) and as usual the Lilypond log was not enough for me.
Thank you David
