The font can be changed to small caps.

staffLineLayoutFunction is used to change the position of notes. This snippet shows setting its value to ly:pitch-semitones in order to produce a chromatic scale with the distance between each space and line of the stave equal to one semitone.

The number of augmentation dots on a single note can be changed independently of the dots placed after the note.

The number of lines in a staff may changed by overriding the StaffSymbol property line-count.

Accidentals and plus signs can appear before or after the numbers, depending on the figuredBassAlterationDirection and figuredBassPlusDirection properties.

If plus signs appear after the number, specially designed glyphs are provided for some figures.

To change the size of an individual staff, you would \set the fontSize property of the Staff context, and \override the 'staff-space, and 'thickness properties of the StaffSymbol.

This snippet shows how to simplify this process by defining a music function called staffSize. It works as a macro and sets each of these three properties for you. (It can actually be used in any context that has a font size engraver, not just Staff contexts.)

If you want to resize all the staves in the file (and all the text as well), a simpler way is to use #(set-global-staff-size xx).

The font-size property can be set directly, so that only certain layout objects are affected.

It is possible to change the fontsize of note heads.

The size and thickness of woodwind diagrams can be changed.

Though the simplest way to resize staves is to use #(set-global-staff-size xx), an individual staff's size can be changed by scaling the properties 'staff-space and fontSize.
