Unfretted string instruments


Creating slurs across voices

In some situations, it may be necessary to create slurs between notes from different voices. The solution is to add invisible notes to one of the voices, using \hideNotes.

This example is measure 235 of the Ciaconna from Bach’s 2nd Partita for solo violin, BWV 1004.

\relative c' {
  <<
    {
      d16( a') s a s a[ s a] s a[ s a]
    }
    \\
    {
      \slurUp
      bes,16[ s e](
      \hideNotes a)
      \unHideNotes f[(
      \hideNotes a)
      \unHideNotes fis](
      \hideNotes a)
      \unHideNotes g[(
      \hideNotes a)
      \unHideNotes gis](
      \hideNotes a)
    }
  >>
}

Dotted harmonics

Artificial harmonics using \harmonic do not show dots. To override this behavior, set the context property harmonicDots.

\relative c''' {
  \time 3/4
  \key f \major
  \set harmonicDots = ##t
  <bes f'\harmonic>2. ~
  <bes f'\harmonic>4. <a e'\harmonic>8( <gis dis'\harmonic> <g d'\harmonic>)
  <fis cis'\harmonic>2.
  <bes f'\harmonic>2.
}

Snap-pizzicato or Bartok pizzicato

A snap-pizzicato (also known as “Bartok pizzicato”) is a “strong pizzicato where the string is plucked vertically by snapping and rebounds off the fingerboard of the instrument” (Wikipedia). It is denoted by a circle with a vertical line going from the center upwards outside the circle.

\relative c' {
  c4\snappizzicato
  <c' e g>4\snappizzicato
  <c' e g>4^\snappizzicato
  <c, e g>4_\snappizzicato
}

Modello per quartetto d’archi (semplice)

Questo modello presenta un semplice quartetto d’archi. Impiega anche una sezione \global per definire il tempo e l’armatura di chiave.

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

violinOne = \new Voice \relative c'' {
  c2 d
  e1
  \bar "|."
}

violinTwo = \new Voice \relative c'' {
  g2 f
  e1
  \bar "|."
}

viola = \new Voice \relative c' {
  \clef alto
  e2 d
  c1
  \bar "|."
}

cello = \new Voice \relative c' {
  \clef bass
  c2 b
  a1
  \bar "|."
}

\score {
  \new StaffGroup <<
    \new Staff \with { instrumentName = "Violin 1" }
    << \global \violinOne >>
    \new Staff \with { instrumentName = "Violin 2" }
    << \global \violinTwo >>
    \new Staff \with { instrumentName = "Viola" }
    << \global \viola >>
    \new Staff \with { instrumentName = "Cello" }
    << \global \cello >>
  >>
  \layout { }
  \midi { }
}

Modello per quartetto d’archi con parti separate

Il frammento di codice del “Modello per quartetto d’archi” crea un bel quartetto, ma cosa fare se si ha bisogno di creare le singole parti? Questo nuovo modello mostra come usare la funzionalità \tag per dividere facilmente un pezzo in parti staccate.

Occorre dividere questo modello in file separati; i nomi dei file sono indicati nei commenti all’inizio di ogni file. piece.ly contiene tutte le definizioni musicali. Gli altri file – score.ly, vn1.ly, vn2.ly, vla.ly e vlc.ly – creano ciascuna parte.

Non dimenticare di togliere i commenti quando usi i file separati!
