Override commands are often long and tedious to type, and they
have to be absolutely correct. If the same overrides are to be
used many times it may be worth defining variables to hold them.
Suppose we wish to emphasize certain words in lyrics by printing
them in bold italics. The \italic
and \bold
commands do not work within lyrics so we must instead use the
following \override
and \revert
commands:
\override Lyrics . LyricText #'font-shape = #'italic
\override Lyrics . LyricText #'font-series = #'bold
\revert Lyrics . LyricText #'font-shape
\revert Lyrics . LyricText #'font-series
These would be extremely tedious to enter if there were many words requiring emphasis. So instead we define these as two variables, and use them as follows:
emph = { \override Lyrics . LyricText #'font-shape = #'italic \override Lyrics . LyricText #'font-series = #'bold } norm = { \revert Lyrics . LyricText #'font-shape \revert Lyrics . LyricText #'font-series } global = { \time 4/4 \partial 4 \key c \major} SopMusic = \relative c' { c4 | e4. e8 g4 g | a a g } AltoMusic = \relative c' { c4 | c4. c8 e4 e | f f e } TenorMusic = \relative c { e4 | g4. g8 c4. b8 | a8 b c d e4 } BassMusic = \relative c { c4 | c4. c8 c4 c | f8 g a b c4 } VerseOne = \lyrics { E -- | ter -- nal \emph Fa -- ther, \norm | strong to save, } VerseTwo = \lyricmode { O | \emph Christ, \norm whose voice the | wa -- ters heard, } VerseThree = \lyricmode { O | \emph Ho -- ly Spi -- rit, \norm | who didst brood } VerseFour = \lyricmode { O | \emph Tri -- ni -- ty \norm of | love and pow'r } \score { \new ChoirStaff << \new Staff << \clef "treble" \new Voice = "Sop" { \voiceOne \global \SopMusic } \new Voice = "Alto" { \voiceTwo \AltoMusic } \new Lyrics \lyricsto "Sop" { \VerseOne } \new Lyrics \lyricsto "Sop" { \VerseTwo } \new Lyrics \lyricsto "Sop" { \VerseThree } \new Lyrics \lyricsto "Sop" { \VerseFour } >> \new Staff << \clef "bass" \new Voice = "Tenor" { \voiceOne \TenorMusic } \new Voice = "Bass" { \voiceTwo \BassMusic } >> >> }
