Before moving to computer science, I was a cello teacher. And I'm
now playing first violin in an orchestra doing, amongst other
things, Tchaik's Romeo and Juliet. I also played viola for half
of my music degree. I'm very familiar with (bowed) string music.

There's a couple of separate issues here:
- what is the precise definition of a "chord" according to an
arbitrary violinist?
- what is the precise definition of a "chord" according to an
expert in music notation?
- what is the precise definition of a "chord" according to the
lilypond manual?
- what is the precise definition of a "chord" according to the
lilypond internal code (be it scheme or C++)?

Look, if you want to get a violinist "chord", you do this:
\new Staff \relative c'' {
<<
{ \voiceOne g,4 }
{ \voiceOne d'4 }
{ \voiceOne b'4 }
{ \voiceOne g'2 }
>>
}
not hard. Wrap it up in a music function to make it easier.
If somebody wants to work on adding such a music function to
lilypond itself, send an email to the frog list, or a patch to the
-devel list. If somebody wants to talk about the lilypond input
syntax -- such as making the <> construct allow different
durations -- then wait until GLISS.
