### 4.5.3 Changing horizontal spacing

Horizontal spacing may be altered with the `base-shortest-duration` property. Here we compare the same music; once without altering the property, and then altered. Larger values of `ly:make-moment` will produce smaller music. Note that `ly:make-moment` constructs a duration, so `1 4` is a longer duration than `1 16`.

```\score {
\relative {
g'4 e e2 | f4 d d2 | c4 d e f | g4 g g2 |
g4 e e2 | f4 d d2 | c4 e g g | c,1 |
d4 d d d | d4 e f2 | e4 e e e | e4 f g2 |
g4 e e2 | f4 d d2 | c4 e g g | c,1 |
}
}
```

```\score {
\relative {
g'4 e e2 | f4 d d2 | c4 d e f | g4 g g2 |
g4 e e2 | f4 d d2 | c4 e g g | c,1 |
d4 d d d | d4 e f2 | e4 e e e | e4 f g2 |
g4 e e2 | f4 d d2 | c4 e g g | c,1 |
}
\layout {
\context {
\Score
\override SpacingSpanner.base-shortest-duration = #(ly:make-moment 1/16)
}
}
}
```

#### Selected Snippets

By default, spacing in tuplets depends on various non-duration factors (such as accidentals, clef changes, etc). To disregard such symbols and force uniform equal-duration spacing, use `Score.SpacingSpanner.uniform-stretching`. This property can only be changed at the beginning of a score,

```\score {
<<
\new Staff {
\tuplet 5/4 { c8 c c c c } c8 c c c
}
\new Staff {
c8 c c c \tuplet 5/4 { c8 c c c c }
}
>>
\layout {
\context {
\Score
\override SpacingSpanner.uniform-stretching = ##t
}
}
}
```

When `strict-note-spacing` is set, notes are spaced without regard for clefs, bar lines, and grace notes,

```\override Score.SpacingSpanner.strict-note-spacing = ##t
\new Staff \relative {
c''8[ c \clef alto c \grace { c16 c } c8 c c]  c32[ c] }
```
