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> <p> <a href="../90/lily-7a9a00ba.ly"> <img align="middle" border="0" src="../90/lily-7a9a00ba.png" alt="[image of music]"> </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> <p> <a href="../90/lily-228d00b7.ly"> <img align="middle" border="0" src="../90/lily-228d00b7.png" alt="[image of music]"> </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 } >> </pre> <p> <a href="../f9/lily-f8c3ab9c.ly"> <img align="middle" border="0" src="../f9/lily-f8c3ab9c.png" alt="[image of music]"> </a> </p> </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'> } >> </pre> <p> <a href="../64/lily-cfbe2c18.ly"> <img align="middle" border="0" src="../64/lily-cfbe2c18.png" alt="[image of music]"> </a> </p> </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> <a href="../01/lily-8e2f5b54.ly"> <img align="middle" border="0" src="../01/lily-8e2f5b54.png" alt="[image of music]"> </a> </p> </blockquote> <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.
