Using double slurs for legato chords
Some composers write two slurs when they want legato chords. This can be achieved by setting
doubleSlurs.
\relative c' {
\set doubleSlurs = ##t
4( )
}
Using the whiteout property
Any graphical object can be printed over a white background to mask parts of objects that
lie beneath. This can be useful to improve the appearance of collisions in complex situations
when repositioning objects is impractical. It is necessary to explicitly set the layer property to
control which objects are masked by the white background.
In this example the collision of the tie with the time signature is improved by masking
out the part of the tie that crosses the time signature by setting the whiteout property of
TimeSignature. To do this TimeSignature is moved to a layer above Tie, which is left in
the default layer of 1, and StaffSymbol is moved to a layer above TimeSignature so it is not
masked.

\override Score.StaffSymbol #'layer = #4
\override Staff.TimeSignature #'layer = #3

\once \override Staff.TimeSignature #'whiteout = ##t

Vertical line as a baroque articulation mark
This short vertical line placed above the note is commonly used in baroque music. Its meaning
can vary, but generally indicates notes that should be played with more “weight”. The following
example demonstrates how to achieve such a notation.
upline =
#(let ((m (make-articulation "stopped")))
(set! (ly:music-property m 'tweaks)
(acons 'font-size 3
(acons 'stencil (lambda (grob)
