Partial measures, for example in upsteps, are entered using the
\partial
command
\partial 16*5 c16 cis d dis e | a2. c,4 | b2
The syntax for this command is
\partial duration
This is internally translated into
\set Timing.measurePosition = -length of duration
The property measurePosition
contains a rational number
indicating how much of the measure has passed at this point.
This command does not take into account grace notes at the start of
the music. When a piece starts with graces notes in the pickup, then
the \partial
should follow the grace notes
{ \grace f16 \partial 4 g4 a2 g2 }
