我正在使用 Lilypond 中的乐谱，它有很多重复，基本上每个小节都必须重复一定次数。我希望能够在每个条形上方写下它应该重复的次数，类似于下面的分数（不是在 Lilypond 中创建的）：
能够在条形上方放置一些括号并且将“3x”集中起来会很棒，就像上面的示例一样。到目前为止，我能够在 Lilypond 中提出的唯一（临时）解决方案是添加重复小节，然后在每个小节的第一个音符上方简单地写“3x”（因为我也无法将它集中在小节上） . 它看起来不太好，但可以完成工作。这个临时解决方案如下所示：
任何关于如何使这个例子看起来更类似于第一家旅馆 Lilypond 的建议都将非常受欢迎！
这是此问题的解决方法：

这个解决方案不是我自己创建的，而是由 David Nalesnik 从 lilypond-user 邮件列表发送给我的。我只是想在这里分享它，以防有人也需要它。我对大卫发给我的内容做了一些非常小的调整。
我刚刚遇到了类似的问题，但更喜欢第二个示例中的样式，条形上方的 3x。我找到的解决方案是：
f e d c |
\mark \markup {"3x"}\repeat volta 3 {c d e f}
f e d c |

也许别人有它的用处。
