3.2.92 spacing-spanner-interface

The space taken by a note is dependent on its duration. Doubling a duration adds spacing-increment to the space. The most common shortest note gets shortest-duration-space. Notes that are even shorter are spaced proportonial to their duration.

Typically, the increment is the width of a black note head. In a piece with lots of 8th notes, and some 16th notes, the eighth note gets a 2 note heads width (i.e., the space following a note is a 1 note head width). A 16th note is followed by 0.5 note head width. The quarter note is followed by 3 NHW, the half by 4 NHW, etc.

User settable properties:

average-spacing-wishes (boolean)

If set, the spacing wishes are averaged over staves.

base-shortest-duration (moment)

Spacing is based on the shortest notes in a piece. Normally, pieces are spaced as if notes at least as short as this are present.

common-shortest-duration (moment)

The most common shortest note length. This is used in spacing. Enlarging this sets the score tighter.

packed-spacing (boolean)

If set, the notes are spaced as tightly as possible.

shortest-duration-space (dimension, in staff space)

Start with this much space for the shortest duration. This is expressed in spacing-increment as unit. See also spacing-spanner-interface.

spacing-increment (number)

Add this much space for a doubled duration. Typically, the width of a note head. See also spacing-spanner-interface.

strict-grace-spacing (boolean)

If set, main notes are spaced normally, then grace notes are put left of the musical columns fot the main notes.

strict-note-spacing (boolean)

If set, unbroken columns with non-musical material (clefs, bar lines, etc.) are not spaced separately, but put before musical columns.

uniform-stretching (boolean)

If set, items stretch proportionally to their durations. This looks better in complex polyphonic patterns.
