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:

     music = {
       g8 d' g'\5 a b g e d' |
       g4 d''8\5 b' a'\2 g'\5 e'\2 d' |
       g4
     }

     <<
       \new Staff \with { \omit StringNumber }
       { \clef "treble_8"  \music }
       \new TabStaff \with {
         tablatureFormat = #fret-number-tablature-format-banjo
         stringTunings = #banjo-open-g-tuning
       }
       { \music }
     >>


The definition is:

(define-public (fret-number-tablature-format-banjo
                context string-number fret-number)
  (make-vcenter-markup
   (number->string (cond
                    ((and (> fret-number 0) (= string-number 5))
                     (+ fret-number 5))
                    (else fret-number)))))

So this is intentional (don't know how to play the banjo).  What kind of
6-string banjo do you actually use here?
