articulations above ledger lines

[Gilberto Agostinho]

Hi all,

According to Elaine Gould's /Behind Bars/, articulations should not 
obscure ledger lines. I believe this is quite justifiable as though we 
want them as close as possible to the note heads for quick recognition, 
they make pitch identification much more difficult when many ledger 
lines are in use. At the moment, in order to avoid this the user is 
required to manually correct the output, see code below:


\version "2.19.81"

\markup{"articulations shouldn't obscure the ledger lines"}

{
  \override Beam.auto-knee-gap = #14
   c''''8 e-^ e-. e-!
}

\markup{"a better solution be"}

{
  \override Beam.auto-knee-gap = #14
   c''''8
   \override Script.Y-offset = #-2.5
   e-^ e-. e-!
}

If anyone would like to take a look at the mentioned passage of Gould's 
book, I will be happy to send a photograph of that page.

Best wishes,
