This answer has already been answered to some extent by clemens with his additional last comments on that other post on guitar tablature typesetting. This is just a way of tackling the issue and to solve the problem with more detail and later on it may be proper to close or erase this post, due to lack of attention or perhaps usefulness.
Summing up, it's possible to do tablatures.
The two answers are, again by clemens:
\Str{2}{11} means eleventh fret of the second string
\Notes\str{6}{7}\Str{3}{6}\en is a two-note chord
Still, it'd be neat to get a cue on the underlying logic to other additional elements in this code. How can the spacing between notes be controlled? We need to combine the \hsk / \sk elements together with \STr \Str \str. How would one combine them so that the notes appear the closest together?
This mwe tries to show an approximation but still fails. Because the first two combinations of notes are close to the following but not so with the next ones...
