Halas, my web server is under raspberry pi which has only lilypond
2.18.2. But 2.18.2 does not give a suitable output (too many natural
signs).
Try that:
\version "2.18.2"
{
  \override AccidentalCautionary.parenthesized = ##f
  \accidentalStyle teaching
  \key d \major
  d'4 fis' d' fis' d'4 fis' d' fis'
}
and you'll get a natural sign on second, third and fourth d. But it's
perfectly fine on 2.19.84.

Any possibility to install a more recent version of lilypond on
raspberry or to make it work on 2.18.2?

Thanks
