Re: \rightHandFinger in banjo tablature

[Thomas Widmann]

Hello,

it's me again with a follow-up question: I've now added \stemDown and
adjusted the concaveness to make the banjo tablature look more like I
want it. However, ideally I'd want all the right hand fingerings
aligned on one line, but they keep jumping up and down (because of
where the beams end). I've played around with
Stem.details.beamed-lengths and
Stem.details.beamed-minimum-free-lengths, but it's still not looking
right.

Any ideas? Here's my code:

fT = \rightHandFinger #1
fI = \rightHandFinger #2
fM= \rightHandFinger #3

music = {
gis16\fT
  (\glissando a)
  b8 \fI
  g'\5\fT
  d' \fM
  g \fT
  b \fI
  g'\5 \fT
  d' \fM
  |
  c'4 \fI
  g'8\5 \fT
  c' \fI
  e' \fM
  g'\5 \fT
  c' \fI
  e' \fM
}

 \new TabStaff \with { \tabFullNotation
    tablatureFormat = #fret-number-tablature-format-banjo
    stringTunings = #banjo-open-g-tuning
  \consists New_fingering_engraver
  \override StrokeFinger.digit-names = ##("T" "I" "M" "R" "P")
strokeFingerOrientations = #'(down)
}{
  \stemDown
  \override Beam.concaveness = #10000
  \music
}
