I guess you could wrap the tied notes into a polyphonic structure
(where the additional voice has only hidden notes) and then specify
the exact location of the upbow, like so:
Instead of eg
c''2. ~ c2.
use
<<
{ c''2. ~ c''2. }
\new Voice { \hide c''2.\downbow \hide c''2.\upbow }
>>
IIUC, this should be:
{
c''2.\downbow ~
<<
{ c''2. }
\new Voice { s4. s\upbow }
>>
}
Note the use of ‘s’, a spacer rest, which is semantically more correct
than \hide c''.
It’s possible to nicely wrap this into a music function:
%%%%%%%%%
\version "2.19.25"
% music function by Simon Albrecht after an idea of David Kastrup
after = #(define-music-function (t e m) (ly:duration? ly:music? ly:music?)
#{ << #m { \skip $t <> -\tweak extra-spacing-width #empty-interval
$e } >> #})
\relative {
c''2.\downbow ~
%% read: after the duration of a dotted fourth note, change to upbow,
during the following note
\after 4. \upbow c
}
%%%%%%%%%
It’s an invaluable tool also for dynamics.
Yours, Simon
