Re: remove individual ledger line?

[Mark Polesky]

So sorry, I'm having trouble with my email client again, hope this works.


I wrote:
> How do I tweak an individual ledger line from within a chord?

Well, an hour later, and all I've managed to achieve is printing the
staff-positions of the ledger lines that happen to have noteheads on
them (to the standard output), and while that makes me feel like a
minor genius, it seems I haven't gotten any closer to being able to
tweak these things individually.

Worse yet, I see my initial question doesn't even capture the full
extent of what I'm trying to do here.  What I want to be able to do
is to tweak individual ledger lines, even if they don't have a note
attached to them.  For example, in...

{ a }

...there are 2 ledger lines below the treble staff to accomodate the
a-natural; I want to tweak both individually.  There must be a way!

Does anyone know?  Even a nudge in the right direction would help.

Thanks,
Mark
