 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{stringTuning} are the
 numbers of semitones to subtract or add, starting the specified pitch

+LilyPond comes with predefined string tunings for banjo, guitar and bass guitar.

+The default string tuning is @code{guitar-tuning} (the standard EADGBE tuning).

+@code{mandolin-tuning} and @code{banjo-open-g-tuning}.

+
+LilyPond has basic support for five stringed banjo.  When making tablatures
+for five stringed banjo, use the banjo tablature format function to get correct
+fret numbers for the fifth string:
+
+@lilypond[quote,ragged-right,fragment,verbatim]
+\new TabStaff <<
+  \set TabStaff.tablatureFormat = #fret-number-tablature-format-banjo
+  \set TabStaff.stringTunings = #banjo-open-g-tuning

+    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
