按音调在 Lilypond 中着色笔记答案

【问题标题】：Coloring notes in Lilypond by pitch按音调在 Lilypond 中着色笔记
【发布时间】：2023-03-18 22:12:02
【问题描述】：

lilypond可以任意给笔记上色using

\override NoteHead #'color = #red c

默认颜色为黑色。但我喜欢按音高给所有音符上色，这样我的孩子们就可以更容易地学会识别音符，因为 c、d、e、f ……与它自己的颜色相关联。以上允许我这样做，但相当冗长。

是否有捷径，某种宏，可以让我按照以下方式做一些事情：

redc greend bluee

甚至按音高覆盖每个音符的默认颜色，这样我什至可以简单地做：

c d e

每个人都有不同的颜色吗？

根据我的经验，与 Sibelius 相比，它相当痛苦。到目前为止，我已经用这两种方式完成了音乐排版，但我更喜欢图形化的方式:)
我几乎是一个音乐爱好者...... Lilypond 可以满足我的需求，在 Linux 上运行，而且是免费的。

snippets 中有一个例子：

%Association list of pitches to colors.
#(define color-mapping
  (list
    (cons (ly:make-pitch 0 0 0) (x11-color 'red))
    (cons (ly:make-pitch 0 0 1/2) (x11-color 'green))
    (cons (ly:make-pitch 0 1 -1/2) (x11-color 'green))
    (cons (ly:make-pitch 0 2 0) (x11-color 'red))
    (cons (ly:make-pitch 0 2 1/2) (x11-color 'green))
    (cons (ly:make-pitch 0 3 -1/2) (x11-color 'red))
    (cons (ly:make-pitch 0 3 0) (x11-color 'green))
    (cons (ly:make-pitch 0 4 1/2) (x11-color 'red))
    (cons (ly:make-pitch 0 5 0) (x11-color 'green))
    (cons (ly:make-pitch 0 5 -1/2) (x11-color 'red))
    (cons (ly:make-pitch 0 6 1/2) (x11-color 'red))
    (cons (ly:make-pitch 0 1 0) (x11-color 'blue))
    (cons (ly:make-pitch 0 3 1/2) (x11-color 'blue))
    (cons (ly:make-pitch 0 4 -1/2) (x11-color 'blue))
    (cons (ly:make-pitch 0 5 1/2) (x11-color 'blue))
    (cons (ly:make-pitch 0 6 -1/2) (x11-color 'blue))
    ))

%Compare pitch and alteration (not octave).
#(define (pitch-equals? p1 p2)
  (and
    (= (ly:pitch-alteration p1) (ly:pitch-alteration p2))
    (= (ly:pitch-notename p1) (ly:pitch-notename p2))))

#(define (pitch-to-color pitch)
  (let ((color (assoc pitch color-mapping pitch-equals?)))
    (if color
      (cdr color))))

#(define (color-notehead grob)
  (pitch-to-color
    (ly:event-property (ly:grob-property grob 'cause) 'pitch)))

\score {
  \new Staff \relative c' {
    \override NoteHead #'color = #color-notehead
    c8 b d dis ees f g aes
  }
}

It is possible to color note heads depending on their pitch?LilyPond Snippet Repository 有一个问题。您可以通过单击五线谱获得the answer。

【讨论】：

我看过那个例子，但显然没有足够的音乐素养来识别这与键盘上的音高变化不同 :) 这确实有效！

好的，对于我今年早些时候在剑桥买的书Kid's Keyboard Course - Book #1，我现在有了这个颜色编码：

#(define color-mapping
  (list
    (cons (ly:make-pitch 0 0 0) (x11-color 'magenta))
    (cons (ly:make-pitch 0 1 -1/2) (x11-color 'grey))
    (cons (ly:make-pitch 0 1 0) (x11-color 'grey))
    (cons (ly:make-pitch 0 1 1/2) (x11-color 'grey))
    (cons (ly:make-pitch 0 2 0) (x11-color 'red))
    (cons (ly:make-pitch 0 2 1/2) (x11-color 'red))
    (cons (ly:make-pitch 0 3 -1/2) (x11-color 'green))
    (cons (ly:make-pitch 0 3 0) (x11-color 'green))
    (cons (ly:make-pitch 0 4 -1/2) (x11-color 'blue))
    (cons (ly:make-pitch 0 4 0) (x11-color 'blue))
    (cons (ly:make-pitch 0 4 1/2) (x11-color 'blue))
    (cons (ly:make-pitch 0 5 0) (x11-color 'yellow))
    (cons (ly:make-pitch 0 5 -1/2) (x11-color 'yellow))
    (cons (ly:make-pitch 0 5 1/2) (x11-color 'yellow))
    (cons (ly:make-pitch 0 6 1/2) (x11-color 'purple))
    (cons (ly:make-pitch 0 6 0) (x11-color 'purple))
    (cons (ly:make-pitch 0 6 -1/2) (x11-color 'purple))))
