Re: what did I wrong?

Thank you for answering.

I confirm, that the Banjo TABs will show correctly, I used it quite
often in the past in g tuning and different tunings as well. I. e. the
usual old time sawmill tuning   
sawmill = \stringTuning < g' c g c' d' >.

I need TABs for a Guitar tuned in perfect fourth  
fourth = \stringTuning < e a d' g' c'' f'' > .
In the example I used   
oud = \stringTuning < f a d' g' c'' f'' >,
the usual  tuning of the arabic Oud. There are turkish variants as well,
that differ with a third step on different positions. Actually not a topic.

Anyway, obviously there is a bug(?) as the a on the a string will show
correctly in the TAB, but  for b, c .... will be added a fifth. If I
transpose the example an octave, it will be show correctly.
  
\version "2.18.2"

#(set-global-staff-size 27)             %%% System
  
   fourth =  \stringTuning < f a d' g' c'' f'' >
  
   Scale= {
          %\relative c
    \override Score.BarNumber.break-visibility = ##(#t #t #t)
    \time 4/4
   {
    \transpose f, f
    {
     f, g, a, b, | c d e f | 
    a d e f |   % with string definition
    }

         \bar "|."
    }
   }
   
    \new TabStaff \with {
    \tabFullNotation
    \stemDown
    tablatureFormat = #fret-number-tablature-format-banjo
    stringTunings = #fourth 
    }
    {
      \Scale
  }
