Hammer-on and pull-off using chords

When using hammer-on or pull-off with chorded notes, only a single arc is drawn. However “double arcs” are possible by setting the doubleSlurs property to #t.

\version "2.24"

\new TabStaff {
  \relative c' {
    % chord hammer-on and pull-off
    \set doubleSlurs = ##t
    <g' b>8( <a c> <g b>)
  }
}
