  • c4 and tenor are equivalent and represent a bratsche clef on the 4th staff line
  • c1, c2, c3, c5 represent a bratsche clef on the 1st, 2nd, 3rd and 5th staff line
  • c0 represent a bratsche clef on the 1st ledger line under the staff
  • g, g2, treble, violin are equivalent and represent a G clef on the 2nd staff line

  • gg1, gg3, gg4, gg5 represent a double G clef on the 1st, 3rd, 4th and 5th staff line
  • perc, perc3 are equivalent and represent a percussion clef on the 3rd staff line
  • perc1, perc2, perc4, perc5 represent a percussion clef on the 1st, 2nd, 4th and 5th staff line
  • none, off prevents the clef to be displayed

See the Clefs example.


\key


Description

Name Variants Type Notation element
\key P key signatures

The \key tag displays a key signature specified as tonality or as a number of sharps or flats. It supports also arbitrary keys and micro-tonality.

Parameters

Name Type Description Default value Optional
key string|integer F, C, G, D, A, E, B, H or a signed integer
a free key string
none false
hideNaturals string a boolean value to prevent naturals on key change false true
free string a free key string none true
  • when specified with a signed integer, positive values are for sharps and negative values for flat
  • F is equivalent to -1
  • C, G, D, A, E are respectively equivalent to 0, 1, 2, 3 and 4
  • B and H are equivalent to 5
  • a free key string is an arbitrary list of notes with accidentals separated by spaces. When not indicated, an accidental takes the previous value, Accidentals support micro-tonality using signed floating point numbers inside brackets. Example: "g#d&" denotes a key signature with a 'g' sharp and a 'd' flat; "f[0.5]c" denotes a key with a quarter tone sharp on 'f' and 'c'.

See the Key example.


\meter


Description

Name Variants Type Notation element
\meter P time signatures

The \meter tag displays a time signature.

Parameters

Name Type Description Default value Optional
type string C, c, C/, c/
a rational string
a complex time signature string
4/4 false
autoBarlines boolean control automatic barlines on true
autoMeasuresNum string on, off, system, page off true
group boolean control complex meter appearance off true
  • C, c, C/, c/ : a C or a crossed C meter.
  • complex time strings are in on of the following forms:
    • a) "a+b+...+n/d" a rational with a sum as numerator
    • b) "a/b + c/d" a sum of rationals
    • c) a combination of a) and b)
  • autoMeasuresNum activates automatic measures numbering and supports 3 modes:
    • on: the measure number is displayed at every bar
    • system: the measure number is displayed on every system only
    • page: the measure number is displayed on every page only
  • group applies to complex time signatures and control how the a) form encountered in a c) form is displayed: when group if off, the a) form is transformed in a b) form

See the Meter example.
