用lilypond自带案例编命令：给一列音加Staccato

lilypond有一个教学，是如何设计一个命令为音符加accent的，具体可看：

Extending LilyPond: 1.3.4 Adding articulation to notes (example)

 

但是，这个命令只适合加单音，不适合加在一列音上，所以把它稍加改造，可以加到一串音上，这样就能节省很多打代码的时间

例子：给一列音加上断奏记号（staccato）

命令格式：\addStaccato { 音列 }

要命令生效，需要将下面命令区的内容全部复制。

先贴效果，再贴代码

 

效果图：

 

 

 

%%%%%%%%%%%%% 以下是命令区，要使用该命令请复制全部内容 %%%%%%%%%%%%%

%%%%%%%%%%%%% 基础指令区 %%%%%%

#(define (get-elements mymusic)
   (ly:music-property mymusic 'elements)
   )

#(define (get-sequential-music mymusic)
   (ly:music-deep-copy mymusic)
   )

%%%%%%%%%%%%% 根据官方文档改造得来 %%%%%%%%%%%%%%%%

addStaccatoSingle = 
#(define-music-function (note-event) (ly:music?)
  (set! (ly:music-property note-event 'articulations)
        (cons (make-music 'ArticulationEvent
                'articulation-type "staccato")
              (ly:music-property note-event 'articulations)))
  note-event)

%%%%%%%%%%%%% 把单音上的命令运用到音列上 %%%%%%%%%%%%

addStaccato=
#(define-music-function (mymusic) (ly:music?)
   (make-sequential-music
   (map addStaccatoSingle
         (get-elements(ly:music-deep-copy mymusic))
)))

%%%%%%%%%%%%%% 命令区结束，复制到此为止 %%%%%%%%%%%%%%%%%%%%
