the function provided by Robin could serve to adapt snippet 960: http://lsr.di.unimi.it/LSR/Item?id=960 Here's the result: <http://lilypond.1069038.n5.nabble.com/file/n195907/Zwischenablage01.gif> % -------------------------------------------------------------------------- colorOval = #(define-music-function (parser location y-lower y-upper color) (number? number? color?) #{ \once \override HorizontalBracket.Y-offset = #0 \once \override HorizontalBracket.stencil = $(lambda (grob) (let* ( (area (ly:horizontal-bracket::print grob)) (xext (ly:stencil-extent area X)) (xpos (/ (+ (cdr xext) (car xext)) 2)) (xrad (/ (- (cdr xext) (car xext)) 2)) (ypos (/ (+ y-upper y-lower) 2)) (yrad (/ (- y-upper y-lower) 2)) (thick (ly:grob-property grob 'thickness 0.05))) (ly:stencil-translate (ly:make-stencil (list 'ellipse xrad yrad thick #f)) (cons xpos ypos)))) % Use the following properties to modify the appearance: \once \override HorizontalBracket.layer = #-10 \once \override HorizontalBracket.color = $color \once \override HorizontalBracket.thickness = #0.5 \once \override HorizontalBracket.shorten-pair = #'(-1.5 . -1.5) #}) \score { { R1 \colorOval #-5 #1 #green % call this before the first note c'2\startGroup g' c'\stopGroup r2 } \layout { \context { \Voice \consists "Horizontal_bracket_engraver" } } } % -------------------------------------------------------------------------- It can be used to "mark" a sequence of several notes. Lower and upper border must be given as parameters, zero = middle line.
