#### 3.3.3 Clef

The clef indicates which lines of the staff correspond to which pitches.

The clef can be set or changed with the `\clef` command

>          \key f\major  c''2 \clef alto g'2

Supported clef-names include

`treble, violin, G, G2`
  G clef on 2nd line
`alto, C`
  C clef on 3rd line
`tenor`
  C clef on 4th line.
`bass, F`
  F clef on 4th line
`french`
  G clef on 1st line, so-called French violin clef
`soprano`
  C clef on 1st line
`mezzosoprano`
  C clef on 2nd line

`varbaritone`
  F clef on 3rd line
`subbass`
  F clef on 5th line
`percussion`

  tablature clef

By adding `_8` or `^8` to the clef name, the clef is transposed one octave down or up, respectively, and `_15` and `^15` transposes by two octaves. The argument clefname must be enclosed in quotes when it contains underscores or digits. For example,

>          \clef "G_8" c4

This command is equivalent to setting `clefGlyph`, `clefPosition` (which controls the Y position of the clef), `centralCPosition` and `clefOctavation`. A clef is printed when any of these properties are changed.
