Thank you all so much for your help and advice. Given that there might
have been some confusion about what I was asking, I've added below a sort
of template of what I'm doing. Note that this is a duet, and the notes for
the first part (first instrument) are given as variables *_one; and for the
second part (second instrument) as *_two.
The use of the "french" clef is just to check with the original - they will
be changed to "\clef treble" before final typesetting.
What I want to do is to produce a version of this where the second part is
taken by a bass instrument. This will require two things: first a change
of the \global_two decoration, and second a change of relative pitch in its
music.
There are 8 movements, which would mean - in my example - changing the
relative pitch for each variable containing music for this second part.
Given that I like to separate the notes from the movement and instrument
descriptions, I was hoping that this could be done "in one go" as it were.
I was wondering if it would be possible to define one's own version of
\Voice in such a way that included a relative pitch - maybe using a Scheme
function.
Anyway, I shall read all your messages with greater focus later today.
Again, many thanks.
Alasdair
