@node References for fretted strings
@subsubsection References for fretted strings

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. 
Some other elements pertinent to fretted string instruments 
are covered elsewhere:

@itemize
@item Fingerings are indicated with @ref{Fingering instructions}.

@item Instructions for @notation{Laissez vibrer} ties
as well as ties on arpeggios and tremolos is described in
@ref{Ties}.

@item Instructions on handling multiple voices is described 
in @ref{Collision resolution}.

@node String number indications
@subsubsection String number indications

@cindex String numbers

The string on which a note should be played may be indicated by
appending @code{\@var{number}} to a note inside a chord construct
@code{<>}.

@warning{String numbers @strong{must} be defined inside a chord
construct even if there is only a single note.}

<c\5>4 <e\4> <g\3>2
<c,\5 e\4 g\3>1
@end lilypond

When fingerings and string indications are used together, their
placement is controlled by the order in which the two items appear
in the code:

@node Default tablatures
@subsubsection Default tablatures
@cindex Tablatures, basic
@cindex Tablatures, default

Tablature notation is used for notating music for plucked string
instruments.  Pitches are not denoted with note heads, but by
numbers indicating on which string and fret a note must be played.  
LilyPond offers limited support for tablature.

The string number associated with a note is given as a backslash
followed by a number.  By default, string 1 is the highest, 
and the tuning defaults to the standard guitar tuning (with 6 strings).  
The notes are printed as tablature, by using @code{TabStaff} and
@code{TabVoice} contexts

@lilypond[quote,ragged-right,fragment,verbatim]
\new TabStaff {
  a,4\5 c'\2 a\3 e'\1
  e\4 c'\2 a\3 e'\1
}
@end lilypond

@funindex minimumFret
@cindex fret


When no string is specified for a note, the note is assigned to
the lowest string that can generate the note with a fret number
greater than or equal to @code{minimumFret} is selected.  The
default value for @code{minimumFret} is 0.


@lilypond[quote,ragged-right,verbatim]
\new StaffGroup <<
   \new Staff \relative c {
     \clef "treble_8"
     c16 d e f g4
     c,16 d e f g4
   }
   \new TabStaff \relative c {
     c16 d e f g4
     \set TabStaff.minimumFret = #5
     c,16 d e f g4
   }
>>
@end lilypond

@snippets

The direction of stems is controlled the same way in tablature as
in traditional notation. Beams can be made horizontal:

@lilypond[quote,ragged-right,verbatim]
\new TabStaff {
  \relative c {
    g16 b d g
    b d g b
    \stemDown
    \override Beam #'damping = #100000
    g,,16 b d g
    b d g b
  }
}
@end lilypond

Polyphony is created the same way in a @code{TabStaff} as in a
regular staff.

@lilypond[quote,ragged-right,verbatim]

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 = "two" s1
    \new TabVoice = "shared" s1
    \new TabVoice = "solo" s1
    { \melodia }
  >>
>>
@end lilypond


@node Custom tablatures
@subsubsection Custom tablatures
@cindex Tablatures, custom

You can change the tuning of the strings.  A string tuning is
given as a Scheme list with one integer number for each string,
the number being the pitch (measured in semitones relative to
middle C) of an open string.  The numbers specified for
@code{stringTunings} are the numbers of semitones to subtract or
add, starting the specified pitch by default middle C, in string
order.  LilyPond automatically calculates the number of strings by
looking at @code{stringTunings}.

In the next example, @code{stringTunings} is set for the pitches
e, a, d, and g.

@lilypond[quote,ragged-right,fragment,verbatim]
\new TabStaff <<
  \set TabStaff.stringTunings = #'(-5 -10 -15 -20)
  {
    a,4 c' a e' e c' a e'
  }
>>
@end lilypond

LilyPond comes with predefined string tunings for banjo, mandolin,
guitar and bass guitar.  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 Staff <<
    \clef "bass_8"
    \relative c, {
    c4 d e f
    }
  >>
  \new TabStaff <<
    \set TabStaff.stringTunings = #bass-tuning
    \relative c, {
    c4 d e f
    }
  >>
>>
@end lilypond

The default string tuning is @code{guitar-tuning} (the standard
EADGBE tuning).  Some other predefined tunings are
@code{guitar-open-g-tuning}, @code{mandolin-tuning} and
@code{banjo-open-g-tuning}.

@seealso

Snippets:
@rlsr{Fretted strings}.

The file @file{scm/@/output@/-lib@/.scm} contains the predefined string
tunings.

@node Automatic fret diagrams
@subsubsection Automatic fret diagrams
@cindex fret diagrams
@cindex chord diagrams

Fret diagrams can be automatically created from entered notes using the 
@code{FretBoards} context.  This context calculates strings and frets
which can be used to play the notes.

@lilypond[quote,ragged-right,verbatim]
<<
  \context ChordNames {
     \chordmode {

Notes can be explicitly placed on a string.  It is often enough
to place only the lowest note on an explicit string; the rest of 
the notes will then be placed appropriately by the @code{FretBoards}
context.

The strings and frets for the @code{FretBoards} context depend
on the @code{stringTunings} property, which has the same meaning
as in the TabStaff context.  See @ref{Custom tablatures} for 
information on the @code{stringTunings} property. 

The graphical layout of a fret diagram can be customized according to
user preference through the properties of the @code{fret-diagram-interface}.
Details are found at @rinternals{fret-diagram-interface}.  For a 
@code{FretBoards} fret diagram, the interface properties belong to 
@code{FretBoards}.

@snippets
The minimum fret to be used in calculating strings and frets for
the FretBoard context can be set with the @code{minimumFret}
property.

@node Fret diagram markups
@subsubsection Fret diagram markups
@cindex fret diagrams
@cindex chord diagrams

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 markup
interfaces are found at @ref{Text markup commands}.

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 fret-diagram-terse markup string omits string numbers; the string
number is implied by the presence of semicolons.  There is one semicolon 
for each string in the diagram.  The first semicolon corresponds to the
highest string number and the last semicolon corresponds to the first string.
Mute strings, open strings, and fret numbers can be indicated.

short, for example @code{RH},

You may exercise greater control over the placement of right-hand 
fingerings by setting @code{strokeFingerOrientations},

@lilypond[quote,verbatim]
#(define RH rightHandFinger)
\relative c {
  \clef "treble_8"
  \set strokeFingerOrientations = #'(up down)
  <c-\RH #1 e-\RH #2 g-\RH #3 c-\RH #4 > 4
  \set strokeFingerOrientations = #'(up right down)
  <c-\RH #1 e-\RH #2 g-\RH #3 c-\RH #4 > 4
  \set strokeFingerOrientations = #'(left)
  <c-\RH #1 e-\RH #2 g-\RH #3 c-\RH #4 > 2
}
@end lilypond

This example combines left-hand fingering, string indication, and 
right-hand fingering

@lilypond[quote,verbatim]
#(define RH rightHandFinger)
\relative c {
  \clef "treble_8"
  <c-3\5-\RH #1 >4 
  <e-2\4-\RH #2 > 
  <g-0\3-\RH #3 > 
  <c-1\2-\RH #4 >

@node Guitar
@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.

@subsubsection Indicating harmonics and dampened notes

Special note heads can be used to indicate dampened notes or 
harmonics.  Harmonics are normally further explained with a 
text markup.

  \clef "treble_8"
  \override Staff.NoteHead #'style = #'cross

@subsubsection Banjo tablatures
@cindex Banjo tablatures

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,fragment,verbatim]
\new TabStaff <<
  \set TabStaff.tablatureFormat = #fret-number-tablature-format-banjo
  \set TabStaff.stringTunings = #banjo-open-g-tuning
  {
    \stemDown
    g8 d' g'\5 a b g e d' |
    g4 d''8\5 b' a'\2 g'\5 e'\2 d' |
    g4
  }
>>
@end lilypond

A number of common tunings for banjo are predefined in LilyPond:
@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 tunings may be converted to four string banjo tunings using the
@code{four-string-banjo} function:

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