I'm CCing the tablature list, in case anyone (Patrick?) has some suggestions about this doc addition.

I'm not familiar with the terms used by fretted string instrument
musicians, so I'd be very grateful if you or Marc would submit a
suitable documentation suggestion, as decribed here:

http://www.lilypond.org/doc/v2.15/Documentation/contributor/documentation-suggestions

Once the bug squad receive that we can create a tracker for the
Documentation issue.


I would put hammer-on and pull-off in NR 2.4.1, Selected snippets, before "Slides in tablature" (because legato slides use slurs).

Sorry for my bad english...here we go.

## Doc snippet ##

Hammer-on and pull-off can be obtained using slurs. Hammer-on is a raising slur, while pull-off is a falling slur:

\new TabStaff {
  \relative c' {
    d4( e\2)
    a( g)
  }
}


The arc of hammer-on and pull-off is upwards in voice one and three, downwards in voice two and four:

\new TabStaff {
  \relative c' {
    << { \voiceOne g2( a) }
    \\ { \voiceTwo a,( b) }
    >> \oneVoice
  }
}


Hammer-on and pull-off work the same way in chords. By default, only one arc is drawn. You can have a double arc by setting the doubleSlur property to true (be sure to use \once or set it back to false when you don't need it anymore):

\new TabStaff {
  \relative c' {
    % chord hammer-on and pull-off
    \once \set doubleSlurs = ##t
    <g' b>8( <a c> <g b>)
    g( a2) % to check that slur is single again
  }
}
