Music for fretted string instruments is normally notated on
a single staff, either in traditional music notation or in
tablature.  Sometimes the two types are combined, and it is
especially common in popular music to use chord diagrams above
a staff of traditional notation.  The guitar and the banjo are
transposing instruments, sounding an octave lower than written.
Scores for these instruments should use the @code{"treble_8"} clef
(or @code{\transposition c} to get correct MIDI output).
Some other elements pertinent to fretted string instruments
are covered elsewhere:

@cindex tablatures, basic
@cindex tablatures, default

@funindex TabStaff
@funindex TabVoice

Music for plucked string instruments is frequently notated using a
finger/touch notation or tablature.  In contrast to traditional
notation pitches are not denoted with note heads, but by numbers (or
letter-like symbols in historical intavolatura).  The staff lines
in tablature indicate the string on which the note is to be played,
and a number placed on a staff line indicated the fret at which
the corresponding string is to be pressed.
Notes that are to be played simultaneously are vertically aligned.

By default, string 1 is the highest string, and corresponds to the top
line on the @code{TabStaff}.  The tuning of the @code{TabStaff}
strings defaults to the
standard guitar tuning (with 6 strings).  The notes are printed as
tablature, by using @code{TabStaff} and @code{TabVoice} contexts.  A
calligraphic tablature clef is added automatically.

@lilypond[quote,ragged-right,verbatim]
\new TabStaff \relative c' {
  a,8 a' <c e> a
  d,8 a' <d f> a
}
@end lilypond

Default tablatures do not contain any symbols for tone duration nor any
other musical symbols such as e.g. expressive marks.

@lilypond[quote,ragged-right,verbatim]
symbols = {
  \time 3/4
  c4-.^"Allegro" d( e)

@end lilypond

@funindex \tabFullNotation

If all musical symbols used in traditional notation should also show up
in tablature one has to apply the command @code{\tabFullNotation} in a
@code{TabStaff}-context.  Please bear in mind that half notes are
double-stemmed in tablature in order to distinguish them from quarter
notes.

@lilypond[quote,ragged-right,verbatim]

@cindex fret

@funindex minimumFret
@funindex restrainOpenStrings

By default pitches are assigned to the lowest playing position on the
fret-board (first position).  Open strings are automatically preferred.
If you would like a certain pitch to be played on a specific string you
can add a string number indication to the pitch name.  If you don't want
to have string number indications appear in traditional notation, you
can override the respective stencil.  Usually it will be more
comfortable to define the playing position by using the value of
@code{minimumFret}.  The default value for minimumFret is 0.

Even when @code{minimumFret} is set, open strings are used whenever
possible.  This behaviour can be changed by setting @code{restrainOpenStrings}
to @code{#t}.

@lilypond[quote,ragged-right,verbatim]

@funindex \tabChordRepeats
@funindex \chordRepeats
@cindex Chord, repetition
@cindex repetition, using @code{q}

Chord constructs can be repeated by the chord repetition symbol
@code{q}.  In combination with tabulatures, its behavior of removing
string and finger numbers alongside with other events is cumbersome, so
you'll want to run
@example
\chordRepeats #'(string-number-event fingering-event)
@end example
explicitly on music expressions in tabulature using @ref{Chord
repetition}.  This particular command is so common that it is available
as @code{\tabChordRepeats}.

@lilypond[quote,verbatim]
guitar = \relative c' {
  r8 <gis-2 cis-3 b-0>~ q4 q8~ q q4
}

\new StaffGroup <<
  \new Staff {
    \clef "treble_8"
    \guitar
  }
  \new TabStaff {
    \tabChordRepeats \guitar
  }
>>
@end lilypond

Ties over a line break are parenthesized by default.  The same holds for
the second alternative of a repeat.

@lilypond[quote,ragged-right,verbatim]
ties = \relative c' {
  \repeat volta 2 {
    e2. f4~
    f2 g2~
  }
  \alternative {
     { g4 f2. }
     { g4\repeatTie c,2. }

  \layout {
  indent = #0
  ragged-right = ##t

@end lilypond

@funindex \hideSplitTiedTabNotes

The command @code{\hideSplitTiedTabNotes} cancels the behavior of
engraving fret numbers in parentheses:

@lilypond[quote,ragged-right,verbatim]

  \repeat volta 2 {
    e2. f4~
    f2 g2~ }
  \alternative {

@cindex harmonic indications in tablature notation
@cindex tablature and harmonic indications
@funindex \harmonic
@funindex \harmonicByFret
@funindex \harmonicByRatio

Harmonic indications can be added to tablature notation as sounding
pitches:

@lilypond[verbatim,quote]
\layout { \omit Voice.StringNumber }
firstHarmonic = {
  d'4\4\harmonic
  g'4\3\harmonic
  b'2\2\harmonic
}
\score {
  <<
    \new Staff {
      \clef "treble_8"
      \firstHarmonic
    }
    \new TabStaff { \firstHarmonic }
  >>
}
@end lilypond

Note that the command @code{\harmonic} must always be attached to single
notes (possibly inside of a chord) instead of whole chords.
It only makes sense for open-string harmonics
in the 12th fret. All other harmonics should be calculated by LilyPond.
This can be achieved by indicating the fret where a finger of the
fretting hand should touch a string.

@lilypond[verbatim,quote]
fretHarmonics = {
  \harmonicByFret #5 d16\4
  \harmonicByFret #4 d16\4
  \harmonicByFret #3 d8\4
  \harmonicByFret #5 <g\3 b\2>2.
}
\score {
  <<
    \new Staff {
      \clef "treble_8"
      \fretHarmonics
    }
    \new TabStaff { \fretHarmonics }
  >>
}
@end lilypond

Alternatively, harmonics can be computed by defining the ratio of
string lengths above and below the harmonic fingering.

@lilypond[verbatim,quote]
ratioHarmonics = {
  \harmonicByRatio #1/2 <g\3 b\2 e'\1>4
  \harmonicByRatio #1/3 <g\3 b\2 e'\1>4
  \harmonicByRatio #1/4 { g8\3 b8\2 e'4\1 }
}
\score {
  <<
    \new Staff {
      \clef "treble_8"
      \ratioHarmonics
    }
    \new TabStaff { \ratioHarmonics }

Chords are not handled in a special way, and hence the automatic
string selector may easily select the same string for two notes in
a chord.

In order to handle @code{\partcombine}, a @code{TabStaff} must use
specially-created voices:

@lilypond[quote,ragged-right,verbatim]
melodia = \partcombine { e4 g g g } { e4 e e e }
<<
  \new TabStaff <<
    \new TabVoice = "one" s1

    \new TabVoice = "shared" s1
    \new TabVoice = "solo" s1

@funindex stringTunings

LilyPond tablature automatically calculates the fret for
a note based on the string to which the note is assigned.
In order to do this, the tuning of the strings must be
specified.  The tuning of the strings is given in the
@code{stringTunings} property.

LilyPond comes with predefined string tunings for banjo, mandolin,
guitar, bass guitar, ukulele, violin, viola, cello, and double bass.
LilyPond automatically sets
the correct transposition for predefined tunings.  The following
example is for bass guitar, which sounds an octave lower than
written.

@lilypond[quote,ragged-right,verbatim]
<<
  \new Voice \with {
    \omit StringNumber
  } {
    \clef "bass_8"
    \relative c, {
      c4 d e f
    }
  }
  \new TabStaff \with {
    stringTunings = #bass-tuning
  } {
    \relative c, {
      c4 d e f
    }
  }
>>
@end lilypond

The default string tuning is @code{guitar-tuning}, which
is the standard EADGBE tuning.  Some other predefined tunings are
@code{guitar-open-g-tuning}, @code{mandolin-tuning} and
@code{banjo-open-g-tuning}.  The predefined string tunings
are found in @file{ly/string-tunings-init.ly}.

@funindex stringTuning
@funindex \stringTuning
@cindex tablature, custom string tunings
@cindex custom string tunings

Any desired string tuning can be created.  The
@code{\stringTuning} function can be
used to define a string tuning which can be used
to set @code{stringTunings} for the current context.

Its argument is a chord construct
defining the pitches of each string in the tuning.
The chord construct must be in absolute octave mode,
see @ref{Absolute octave entry}.  The string
with the highest number (generally the lowest string) must
come first in the chord.  For example, we can
define a string tuning for a four-string instrument with pitches
of @code{a''},  @code{d''},  @code{g'}, and @code{c'}:

@lilypond[quote,verbatim]

mynotes = {
  c'4 e' g' c'' |
  e''4 g'' b'' c'''
}

<<
  \new Staff {
    \clef treble
    \mynotes
  }
  \new TabStaff {
    \set Staff.stringTunings = \stringTuning <c' g' d'' a''>
    \mynotes
  }
>>
@end lilypond

The @code{stringTunings} property is also used by
@code{FretBoards} to calculate automatic fret diagrams.

String tunings are used as part of the hash key
for predefined fret diagrams
(see @ref{Predefined fret diagrams}).

The previous example could also be written as follows:

@lilypond[quote,verbatim]
custom-tuning = \stringTuning <c' g' d'' a''>

mynotes = {
  c'4 e' g' c'' |
  e''4 g'' b'' c'''
}

<<
  \new Staff {
    \clef treble
    \mynotes
  }
  \new TabStaff {
    \set TabStaff.stringTunings = #custom-tuning
    \mynotes
  }
>>
@end lilypond

Internally, a string tuning is a Scheme list of string pitches,
one for each string, ordered by string number from 1 to N,
where string 1 is at the top of the tablature staff and
string N is at the bottom.  This ordinarily results in ordering
from highest pitch to lowest pitch, but some instruments
(e.g. ukulele) do not have strings ordered by pitch.

A string pitch in a string tuning list is a LilyPond pitch
object.  Pitch objects are created with the Scheme function
@code{ly:make-pitch} (see @ref{Scheme functions}).

@code{\stringTuning} creates such an object from chord input.

LilyPond automatically calculates the number of lines in the
@code{TabStaff} and the number of strings in an automatically
calculated @code{FretBoard} as the number of elements
in @code{stringTunings}.

To let all TabStaff contexts use the same custom tuning by default,
you can use

@example
\layout @{
  \context @{
    \TabStaff
    stringTunings = \stringTuning <c' g' d'' a''>
  @}
@}
@end example

Fret diagrams can be added to music as a markup to the desired
note.  The markup contains information about the desired fret
diagram.  There are three different fret-diagram markup
interfaces: standard, terse, and verbose.  The three interfaces
produce equivalent markups, but have varying amounts of
information in the markup string.  Details about the
syntax of the different markup strings used to define
fret diagrams are found at @ref{Instrument Specific Markup}.

The standard fret diagram markup string indicates the string
number and the fret number for each dot to be placed on the string.
In addition, open and unplayed (muted) strings can be indicated.

The predefined fret diagram table for guitar contains eight chords (major, minor,
augmented, diminished, dominant seventh, major seventh, minor seventh, dominant ninth)
for each of 17 keys.
The predefined fret diagram table for ukulele contains these chords
plus an additional three chords (major sixth, suspended second, and
suspended fourth).
A complete list of the predefined fret diagrams is
shown in @ref{Predefined fretboard diagrams}.  If there is no entry in
the table for a chord, the FretBoards engraver will calculate a

Different fret diagrams for the same chord name can be stored using different

In addition to fret diagrams, LilyPond stores an internal list of chord
shapes.  The chord shapes are fret diagrams that can be shifted along
the neck to different positions to provide different chords.  Chord
shapes can be added to the internal list and then used to define
predefined fret diagrams.  Because they can be moved to various
positions on the neck, chord shapes will normally not contain
any open strings.  Like fret diagrams, chord shapes can be

Sometimes the fretboard calculator will be unable to find
an acceptable diagram.  This can often be remedied by
manually assigning a note to a string.  In many cases, only one
note need be manually placed on a string; the rest of
the notes will then be placed appropriately by the
@code{FretBoards} context.

@subsection Guitar

Most of the notational issues associated with guitar music are
covered sufficiently in the general fretted strings section, but there
are a few more worth covering here.  Occasionally users want to
create songbook-type documents having only lyrics with chord
indications above them.  Since LilyPond is a music typesetter,
it is not recommended for documents that have no music notation
in them.  A better alternative is a word processor, text editor,
or, for experienced users, a typesetter like GuitarTeX.

Power chords and their symbols can be engraved in chord mode or as chord
constructs:

@lilypond[quote,ragged-right,verbatim]
ChordsAndSymbols = {
  \chordmode {
    \powerChords
    e,,1:1.5
    a,,1:1.5.8

Power chord symbols are automatically switched off as soon as one of the
other common chord modifier is used:

LilyPond has basic support for the five-string banjo.  When making tablatures
for five-string banjo, use the banjo tablature format function to get
correct fret numbers for the fifth string:

@c due to crazy intervals of banjo music, absolute pitch is recommended

@lilypond[quote,ragged-right,verbatim]
music = {
  g8 d' g'\5 a b g e d' |
  g4 d''8\5 b' a'\2 g'\5 e'\2 d' |
  g4

A number of common tunings for the five-string banjo are predefined:
@code{banjo-c-tuning} (gCGBD), @code{banjo-modal-tuning} (gDGCD),
@code{banjo-open-d-tuning} (aDF#AD) and @code{banjo-open-dm-tuning}
(aDFAD).

These may be converted to four-string tunings using the
@code{four-string-banjo} function:

@example
\set TabStaff.stringTunings = #(four-string-banjo banjo-c-tuning)
@end example
