A.2 Piano templates


A.2.1 Solo piano

Here is a simple piano staff with some notes.

upper = \relative c'' {
  \clef treble
  \key c \major
  \time 4/4
  
  a4 b c d  
}

lower = \relative c {
  \clef bass
  \key c \major
  \time 4/4
  
  a2 c  
}

\score {
  \new PianoStaff <<
    \set PianoStaff.instrumentName = #"Piano  "
    \new Staff = "upper" \upper
    \new Staff = "lower" \lower
  >>
  \layout { }
  \midi { }
}

A.2.2 Piano and melody with lyrics

Here is a typical song format: one staff with the melody and lyrics, with piano accompaniment underneath.

melody = \relative c'' {
  \clef treble
  \key c \major
  \time 4/4
  
  a b c d  
}

text = \lyricmode {
  Aaa Bee Cee Dee
}

upper = \relative c'' {
  \clef treble
  \key c \major
  \time 4/4
  
  a4 b c d  
}

lower = \relative c {
  \clef bass
  \key c \major
  \time 4/4
  
  a2 c  
}

\score {
  <<
    \new Voice = "mel" { \autoBeamOff \melody }
    \new Lyrics \lyricsto mel \text    
    \new PianoStaff <<
      \new Staff = "upper" \upper
      \new Staff = "lower" \lower
    >>
  >>
  \layout {
    \context { \RemoveEmptyStaffContext }
  }
  \midi { }
}

A.2.3 Piano centered lyrics

Instead of having a full staff for the melody and lyrics, lyrics can be centered between the staves of a piano staff.

upper = \relative c'' {
  \clef treble
  \key c \major
  \time 4/4
  
  a4 b c d  
}

lower = \relative c {
  \clef bass
  \key c \major
  \time 4/4
  
  a2 c  
}

text = \lyricmode {
  Aaa Bee Cee Dee
}

\score {
  \new GrandStaff <<
    \new Staff = upper { \new Voice = "singer" \upper }
    \new Lyrics \lyricsto "singer" \text
    \new Staff = lower { \lower }
  >>
  \layout {
    \context {
      \GrandStaff
      \accepts "Lyrics"
    }
    \context {
      \Lyrics
      \consists "Bar_engraver"
    }
  }
  \midi { }
}

A.2.4 Piano centered dynamics

Many piano scores have the dynamics centered between the two staves. This requires a bit of tweaking to implement, but since the template is right here, you don’t have to do the tweaking yourself.

global = {
  \key c \major
  \time 4/4
}

upper = \relative c'' {
  \clef treble
  a4 b c d
}

lower = \relative c {
  \clef bass
  a2 c
}

dynamics = {
  s2\fff\> s4 s\!\pp
}

pedal = {
  s2\sustainOn s\sustainOff
}

\score {
  \new PianoStaff = "PianoStaff_pf" <<
    \new Staff = "Staff_pfUpper" \upper
    \new Dynamics = "Dynamics_pf" \dynamics
    \new Staff = "Staff_pfLower" << \lower >>
    \new Dynamics = "pedal" \pedal
  >>

  \layout {
    % define Dynamics context
    \context {
      \type "Engraver_group"
      \name Dynamics
      \alias Voice
      \consists "Output_property_engraver"
      \consists "Piano_pedal_engraver"
      \consists "Script_engraver"
      \consists "New_dynamic_engraver"
      \consists "Dynamic_align_engraver"
      \consists "Text_engraver"
      \consists "Skip_event_swallow_translator"
      \consists "Axis_group_engraver"

      pedalSustainStrings = #'("Ped." "*Ped." "*")
      pedalUnaCordaStrings = #'("una corda" "" "tre corde")
      \override DynamicLineSpanner #'Y-offset = #0
      \override TextScript #'font-size = #2
      \override TextScript #'font-shape = #'italic
      \override VerticalAxisGroup #'minimum-Y-extent = #'(-1 . 1)
    }
    % modify PianoStaff context to accept Dynamics context
    \context {
      \PianoStaff
      \accepts Dynamics
    }
  }
}

\score {
  \new PianoStaff = "PianoStaff_pf" <<
    \new Staff = "Staff_pfUpper" << \global \upper \dynamics \pedal >>
    \new Staff = "Staff_pfLower" << \global \lower \dynamics \pedal >>
  >>
  \midi { }
}
