LilyPond Notation Reference: 4.5.3 Changing horizontal spacing

### 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 c'' {
        g4 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 c'' {
        g4 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 {
>           \times 4/5 {
>             c8 c8 c8 c8 c8
>           }
>           c8 c8 c8 c8
>         }
>         \new Staff {
>           c8 c8 c8 c8
>           \times 4/5 {
>             c8 c8 c8 c8 c8
>           }
>         }
>       >>
>       \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 { c8[ c \clef alto c \grace { c16[ c] } c8 c c]  c32[ c32] }
