Fret diagrams can be automatically created from entered notes using the
<code>FretBoards</code> context. If no predefined diagram is available for
the entered notes in the active <code>stringTunings</code>, this context
calculates strings and frets that can be used to play the notes.
<blockquote>
<pre class="verbatim">
<<
\context ChordNames {
\chordmode {
f1 g
}
}
\context FretBoards {
< f, c f a c' f'>1
< g,\6 b, d g b g'>
}
\context Staff {
\clef "treble_8"
< f, c f a c' f'>1
< g, b, d g b' g'>
}
>>
</pre>

</a>
</p>
</blockquote>
<p>As no predefined diagrams are loaded by default, automatic calculation
of fret diagrams is the default behavior. Once default diagrams are
loaded, automatic calculation can be enabled and disabled with predefined
commands:
<blockquote>
<pre class="verbatim">
\storePredefinedDiagram <c e g c' e'>
#guitar-tuning
#"x;3-1-(;5-2;5-3;5-4;3-1-1);"
<<
\context ChordNames {
\chordmode {
c1 c c
}
}
\context FretBoards {
<c e g c' e'>1
\predefinedFretboardsOff
<c e g c' e'>
\predefinedFretboardsOn
<c e g c' e'>
}
\context Staff {
\clef "treble_8"
<c e g c' e'>1
<c e g c' e'>
<c e g c' e'>
}
>>
</pre>

</a>
</p>
</blockquote>
<p>Sometimes the fretboard calculator will be unable to find
an accceptable 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</code>
context.
<blockquote>
<pre class="verbatim">
<<
\context ChordNames {
\chordmode {
c1 c
}
}
\context FretBoards {
< c g c' e' g'> 1
< c g\4 c' e' g'> 1
}
\context Staff {
\clef "treble_8"
< c g c' e' g'> 1
< c g c' e' g'> 1
}

</blockquote>
<p>Fingerings can be added to FretBoard fret diagrams.
<blockquote>
<pre class="verbatim">
<<
\context ChordNames {
\chordmode {
c1 d:m
}
}
\context FretBoards {
< c-3 e-2 g c'-1 e' > 1
< d a-2 d'-3 f'-1>
}
\context Staff {
\clef "treble_8"
< c e g c' e' > 1
< d a d' f'>
}
>>

</blockquote>
<p>The minimum fret to be used in calculating strings and frets for
the FretBoard context can be set with the <code>minimumFret</code>
property.
<blockquote>
<pre class="verbatim">
<<
\context ChordNames {
\chordmode {
d1:m d:m
}
}
\context FretBoards {
< d a d' f'>
\set FretBoards.minimumFret = #5
< d a d' f'>
}
\context Staff {
\clef "treble_8"
< d a d' f'>
< d a d' f'>
}
>>
</pre>

<p>The strings and frets for the <code>FretBoards</code> context depend
on the <code>stringTunings</code> property, which has the same meaning
as in the TabStaff context. See <a href="Custom-tablatures.fr.html#Custom-tablatures">Custom tablatures</a> for
information on the <code>stringTunings</code> property.
<p>The graphical layout of a fret diagram can be customized according to
user preference through the properties of the <code>fret-diagram-interface</code>.
Details are found at <a name="index-fret_002ddiagram_002dinterface-2101"></a><a href="../lilypond-internals/fret_002ddiagram_002dinterface.fr.html#fret_002ddiagram_002dinterface">fret-diagram-interface</a>. For a
<code>FretBoards</code> fret diagram, the interface properties belong to
<code>FretBoards.FretBoard</code>.
