Hey Everybody,
I would like to engrave a polytempical musical material in LilyPond. [...]
Now ideally I would like to see this engraved in a proportional way, so
that the lower staff has a wider spacing, and so the notes are
distributed in the two staves illustrating their exact relation to a
mutual time-scale (so in short: sort of like on the picture above).
Is there any way I can do this?
Hi Bálint,
have a look at section 1.2.3, Polymetric notation in the Notation
Reference (NR):
http://lilypond.org/doc/v2.18/Documentation/notation/displaying-rhythms#polymetric-notation
There is one difference to your example: in the usual approach, there is
only a per-score tempo; the note durations (not appearance) are scaled
to fit this reference metrum. Essentially, you will have one "master
staff" that stays true to time, everything else is scaled to fit.
If you want even more control over horizontal positioning of the notes,
also consider NR sec. 4.5.5:
http://lilypond.org/doc/v2.18/Documentation/notation/proportional-notation
Especially the uniform stretching is highly useful in many contemporary
works; your case ask for strict proportional spacing.
I'm not 100% sure how to fit unique bar line positions per staff into
that picture, though; and I'm not sure whether I like it. To me, measure
numbers and bar positions are a global thing, so I'd rather have a rest
with fermata at the end and a common final barline; in between, I'm unsure.
Is this piece supposed to be conducted by several conductors? Then,
different bar lines make sense, but maybe they could be faked with
breathe marks or something similar; if there is only one conductor, I
feel that the bar lines should be with him, for the entire score.
HTH,
Alexander
