Re: independent spacing

[Mats Bengtsson]

Because of the modular structure of LilyPond, it might be possible to 
obtain what
you describe by moving a number of engravers from the Score level to the
Staff level, but my intuition tells me that it's very likely that you 
break something
fundamental if you really move all spacing related stuff to the Staff 
level.

So, my guess is that it's best to keep to some kind of mathematical 
relationship
between the staves. Then, the simplest solution is to scale the 
durations, for example

kleiner = {\set fontSize = #-3}
normal = {\unset fontSize}
\relative <<
 { \kleiner bes8*5/7_\markup {\italic "as fast as possible"} b bes cis 
s8*8/7 \normal r2 | }
 {\newSpacingSection c4 g' c2 | }
>>

You need some simple math to make the durations match in the end.
For example, in the code above, we have 4 shortened eighth notes that
only take 4*5/7 = 20/7 of the duration of an ordinary eighth note, so to 
fill half
the measure (4*7/7 = 28/7 eighth note durations) you have to fill in with
(28-20)/7 = 8/7 eighth note durations of spacer notes. Alternatively, you
could also have scaled the duration of the half note correspondingly.

I hope you have read the section on Polymetric notation, which explains
different tricks to use in these situations. For example, I could have
used the \compressMusic function instead of scaling each duration 
separately.
Also, if you read the section on Manual beams, you will find some 
information
on the \featherDurations function, which cannot only be used together with
feathered beams, but just scales the duration of each of a sequence of notes
so that the total duration remains the same, but the horizontal placement
corresponds to an accelerando or ritardando with the specified ratio 
between
the duration of the first and last note.
