Finally we come to changing the size of layout objects.
Some layout objects are created as glyphs selected from a typeface font. These include note
heads, accidentals, markup, clefs, time signatures, dynamics and lyrics. Their size is changed
by modifying the font-size property, as we shall shortly see. Other layout objects such as
slurs and ties – in general, spanner objects – are drawn individually, so there is no font-size
associated with them. These objects generally derive their size from the objects to which they
are attached, so usually there is no need to change their size manually. Still other properties
such as the length of stems and bar lines, thickness of beams and other lines, and the separation
of staff lines all need to be modified in special ways.
Returning to the ossia example, let us first change the font-size. We can do this in two ways.
We can either change the size of the fonts of each object type, like NoteHeads with commands
like
\override NoteHead.font-size = #-2
or we can change the size of all fonts by setting a special property, fontSize, using \set, or
by including it in a \with clause (but without the \set).
\set fontSize = #-2
Both of these statements would cause the font size to be reduced by 2 steps from its previous
value, where each step reduces or increases the size by approximately 12%.
Let’s try it in our ossia example:
\new Staff ="main" {
\relative g' {
r4 g8 g c4 c8 d |
e4 r8
